摘要： A polarized fiber laser source includes a fiber laser 10 comprising a pair of Bragg gratings 14,16 at opposite ends of a fiber laser cavity 18 which is doped with a rare-earth dopant so as to allow lasing to occur at a lasing wavelength .lambda..sub.L. A grating tap 26 is provided along a portion of the laser cavity 18 to couple-out a predetermined amount of light along one polarization, e.g., the "s" polarization", at the lasing wavelength .lambda..sub.L. This causes one polarization mode to experience more loss than the other, thereby allowing the fiber laser to lase only on the less lossy polarization mode and causing the laser output light 40 to be polarized only along such polarization.

摘要： A rare earth doped fiber for use in a fiber laser is presented. The fiber laser uses a single stripe broad area pump diode permits Yb lasing in its 3-level transition at 980 nm preferentially over the 1010 nm 4-level transition. The present fiber laser is characterized by a dual cladding fiber geometry which includes an inner rare earth doped single mode core. There is an inner cladding designed to be a multimode pump core for the pump light. The pump core is followed by a final cladding to confine the pump radiation. The present laser matches the larger/outer mode field to that of a single stripe broad area diode in order to maximize the pump intensity.

摘要： An apparatus for use in selectively adding or dropping channels in an optical network includes an optical circulator and an array of programmable fiber Bragg gratings. Each fiber Bragg grating is a narrow ban reflective element which can be tuned on or off of an ITU standard wavelength division multiplex channel so that the channel is either fully reflected or transmitted by the grating. The addition or subtraction of signal channels is operated by a controller which operates the individual fiber Bragg gratings between transmissive and reflective states.

摘要： A dual wavelength pumped low noise fiber laser includes a fiber laser 10 comprising a pair of Bragg gratings 14,16 at opposite ends of a fiber laser cavity 18 which is co-doped with two rare-earth dopants, Er.sup.+3 Yb.sup.+3, so as to allow lasing to occur at a lasing wavelength .lambda..sub.L. A first pump signal 20 efficiently pumps the Yb to the excited state and the Yb energy is transitioned to the Er atoms which ultimately lase at the desire lasing frequency. Because Yb is pumped so efficiently, high pump absorption is achieved, thereby providing high laser output power and, consequently, reduced RIN. Simultaneously, a second pump signal 52 directly pumps the Er at a different wavelength .lambda..sub.P2 which populates the lasing transition more quickly, thereby allowing sufficient bandwidth of a closed loop control on the second pump signal 52 to control low frequency RIN spiking due to relaxation oscillations in the laser.

摘要： A coupled multiple output fiber laser includes a plurality of laser diodes 10,50-56 each providing pump light 12,58-64 which is incident on respective Bragg gratings 16,74-80 which pass the pump wavelength and reflect a lasing wavelength. The fibers 20,90-96 are doped with a gain dopant such as Er.sup.3+ to provide lasing at the lasing wavelength in response to the pump light. Light beams 18,82-88 are incident on an optical coupler 22 which couples the light beams 18,82-88 to the light beams 40-48 on the fibers 30-38 based on a predetermined power distribution, e.g., equal distribution. The light 40 travels along the fiber 30 which acts as a common-cavity fiber. The light 40 reflects off a reflector 120 which provides reflected feedback light 122 which reenters the coupler 22 and is distributed to the individual cavity fibers 20,82-88 based on the same or a different predetermined power distribution. Output light 42-48 is provided on the fibers 32-38 which may be incident on a lens 160 to cause the beams to intersect. The length of each of the fibers 20,90-96 is adjusted by piezoelectric tuners 200-208 to provide coupled cavity phase-locking of the output beams 42-48. Also, each of the output beams 42-48 may be phase shifted by additional tuners 240-246. An additional output beam may be obtained by a light 232 which passes through the mirror 120.

摘要： A detector for laser radiation that detects the presence of above-threshold radiation in one of a set of wavelength ranges employs a set of Fresnel lenses designed to focus radiation in a particular band onto a metal-coated film. A series of Fresnel lenses is designed with constant focal lengths, but each lens is designed to have that focal length at a specific wavelength. Only when the wavelength of the incident radiation matches the design wavelength of the Fresnel lens will the film be marked or machined. Radiation of differing wavelengths will be defocused to a degree that will reduce the intensity below the level that will mark or machine the film. An electronic based version of this spectroscopy detector can also be implemented.

摘要： An integrated optical transmitter for use in an optical system includes an optical head assembly having an optical beam generator for providing an optical beam and a lens assembly for collecting the optical beam and generating therefrom a formed optical beam. Interface optics receive the formed optical beam for coupling the beam to a modulator so as to reduce nsertion loss to the optical beam. The optical modulator receives the optical beam from the interface optics and provides a modulated optical beam in response to received modulation signals. The optical modulator is coupled to the interface optics to be in a fixed relationship therewith. The integrated optical transmitter can include a means for sampling the optical beam and controlling the temperature of and/or the current supplied to the optical beam generator for controlling the wavelength of the optical transmitter. The optical head assembly and the modulator can be compliantly mounted to a mounting surface reducing the effects of thermal stress on the performance of the optical transmitter.

摘要： A fiber laser 26 including a rare-earth doped fiber laser cavity 32 delimited by a pair of reflective elements 28,30, such as Bragg gratings, is tuned by compressing the cavity 32 and the gratings 28,30. Because an optical fiber is a much stronger under compression than in tension, the laser 26 is tunable over a much broader range than conventional tension/stretching techniques.
