摘要： An optical pulse generator, consisting of a semiconductor device and an optical output assembly. The semiconductor device includes an optically-active region having a gain section and a saturable absorber (SA) section, which are adapted to generate coherent optical pulses. The device also includes an output facet for coupling therethrough of the optical pulses generated in the optically-active region, and an SA electrode for application of a radio-frequency (RF) modulation of a desired frequency to the SA section. The optical output assembly is optically coupled to the output facet of the semiconductor device so as to partially reflect the coherent optical pulses within a predetermined wavelength range. The assembly is positioned so as to form, together with the semiconductor device, a laser cavity having a resonant wavelength within the predetermined wavelength range and having an optical length such that a period of the RF modulation substantially equals a round-trip time for one of the pulses in the cavity, whereby the coherent optical pulses are output through the optical output assembly at a repetition rate substantially equal to the RF modulation.

摘要： An optical radiation monitor and an optical amplifier. The radiation monitor consists of an input port which receives the optical radiation, a waveguide, coupled to the input port so as to receive the optical radiation therefrom and adapted to leak a predetermined fraction of the optical radiation, and a photodetector which receives at least some of the leaked optical radiation and which generates a monitoring signal responsive thereto. The optical amplifier consists of an optical gain region which is adapted to output amplified optical radiation responsive to a current injected into the section. The amplifier includes a waveguide coupled to receive the amplified optical radiation and adapted to leak a predetermined fraction of the amplified optical radiation. The amplifier also includes a photodetector which receives at least some of the leaked optical radiation and which generates a monitoring signal responsive thereto, indicative of a performance characteristic of the optical gain region.
