Abstract: In various embodiments, a laser emitter such as a diode bar is cooled during operation via jets of cooling fluid formed by ports in a cooler on which the laser emitter is positioned. The jets strike an impingement surface of the cooler that is thermally coupled to the laser emitter but prevents direct contact between the cooling fluid and the laser emitter itself.

Abstract: In various embodiments, a wavelength beam combining laser system includes a fast-axis collimation lens that is rotated with respect to a plurality of emitters in order to converge the emitted beams onto a dispersive element and/or reduce the size of the multi-wavelength output beam of the system.

Abstract: In various embodiments, wavelength beam combining laser systems incorporate fast-axis collimation lenses and slow-axis collimation lenses (either separately or as portions of a single hybrid lens) optically upstream of an optical rotation system to thereby reduce or minimize cross-talk in the combined output beam.

Abstract: An optical transmitter with chirp control includes an input polarizer having an input that receives an optical signal. The input polarizer polarizes the optical signal along an input polarization axis. A Mach-Zehnder modulator includes an optical input that is coupled to an output of the input polarizer and an electrical input that receives a modulation signal. The Mach-Zehnder modulator modulates the optical signal with the modulation signal. The input polarization axis of the input polarizer is chosen to achieve a desired chirp of the modulated optical signal. An output polarizer is coupled to the output of the Mach-Zehnder modulator. The output polarizer polarizes the modulated optical signal along a desired output polarization axis that combines TE and TM mode polarizations.

Abstract: An optical transmitter is disclosed having a temperature stabilization system for an optical filter for maintaining constant the frequency response of the filter. The filter is mounted within a housing having a substantially higher thermal conductivity. The housing may include a copper-tungsten alloy and extend along the optical axis of the filter. The housing is in thermal contact with a thermo-electric cooler (TEC) and a temperature sensor. The TEC and temperature sensor are electrically coupled to a controller which adjusts the temperature of the TEC according to the output of the temperature sensor.
