摘要： An optical assembly, such as a multiple output diode laser pump source for EDFAs, is formed by pressing an optical array emitter chip against a standoff structure protruding from a submount such that the emitter chip deforms to match the curvature of the standoff structure. An IO chip is also juxtaposed against the standoff structure such that its optical receivers can receive optical energy from the emitter chip. The IO chip can provide various optical functions, and then provide an optical array output for coupling into an optical fiber array. The standoff structure preferably contacts the emitter chip over an aggregate contact area much smaller than the area by which the emitter chip overlaps the submount. The materials used for bonding the emitter chip and the IO chip to the submount are disposed in the recesses between standoffs and not on the contact surfaces of the standoff structure.

摘要： An optical device 1 has a substrate 2, whereas bare fibers 5 exposed from a coated optical fiber tape 3 by removing a coating 4 from its middle part are secured to the upper face part of the substrate 2. In the substrate 2, a transverse groove 8 is formed obliquely with respect to an axis of the bare fibers 5 so as to traverse core parts 5a of the bare fibers. An optical member 9 for reflecting a part of signal light transmitted through the bare fibers 5 is inserted in the transverse groove 8. A support member 10 is provided on the upper side of the bare fibers 5, whereas a support surface 10a of the support member 10 is provided with photodetectors 11 for detecting light reflected by the optical member 9. The support surface 10a of the support member 10 is inclined with respect to the upper face of the substrate 2, whereby the light entrance surface 13 of each photodetector 11 is inclined by a predetermined angle with respect to the upper face of the substrate 2. Such a configuration realizes an optical device which can lower the polarization dependence of received light in the photodetectors.

摘要： A multichannel parallel LD/PD module comprising a bench, a plurality of lightpaths having an initial narrow width region, an intermediate width enlarging region and a final wide width region, a plurality of photodiodes or a photodiode array mounted on the narrow width region, a wavelength selective filter formed on the narrow width region for selectively reflecting receiving beams, a plurality of light emitting devices fitted behind rear ends of the lightpaths on the bench. Traveling in element fibers in an outer ribbon fiber, receiving signal beams go into the lightpaths via front ends and are reflected by the wavelength selective filter slantingly upward at the narrow width region. The reflected beams go into the photodiodes and are converted into photocurrents in proportion to the receiving signals. Emanating from the light emitting devices, transmitting signal beams enter the lightpaths via final ends of the wide width region, propagate backward in the width enlarging region, arrive at the narrow width region, transfer to outer element fibers in a connector, and propagate in the ribbon fiber following the connector. Long distances between the transmitting portion (LDs or LEDs) and the receiving portion (PDs) suppress optical, electromagnetic and electric crosstalk between the light emitting devices and the photodiodes.

摘要： Optoelectronic modules and methods of manufacturing the same are disclosed. Some of the disclosed modules employ a tape automated bonding substrate (TAB) which is surface mounted with circuit elements. In some examples, the TAB is mounted to a rigid substrate after a fiber submount is passively positioned on the substrate. This modular manufacturing technique limits the value of yield loss. In some example modules, only one active alignment is employed to manufacture the module. Some of the disclosed modules include an optically pluggable connector.

摘要： A package contains therein a semiconductor laser element for emitting light and a semiconductor circuit element for driving the semiconductor laser element and is provided with an optical fiber supporting face and a back face. The optical fiber supporting face is provided for supporting an optical fiber for transmitting the light from the semiconductor laser element, and the back face is opposed to the optical fiber supporting face. The back face has a lead pin for feeding a positive-phase signal into the semiconductor circuit element and a lead pin for feeding a negative-phase signal into the semiconductor circuit element. The lead pins penetrate through the back face. The semiconductor circuit element receives positive-phase and complementary negative-phase signals, both including a high-frequency component of 10 GHz or higher, through the lead pins, converts these signals into a single-ended signal, and outputs the resulting signal to the semiconductor laser element.
