摘要： Optical pumping arrangements are provided for the broadband or multiple wavelength pumping of optical sources. Sources may be based on Raman gain media for amplification. Broadband amplification is provided by using a laser source operating in coherence collapse. Such a source may make use of an optical generator and an output coupler which are sufficiently far apart from one another as to ensure coherence collapse.

摘要： A tunable laser module includes a laser operating at a first wavelength. A wavelength locker includes a planar silica waveguide that is coupled to the laser. The wavelength locker provides an error signal that is used to tune the first wavelength of the laser to a desired wavelength. The wavelength locker and one or more detector(s) generate the error signal based on a difference between the first wavelength value and the desired wavelength value. A controller is connected to the waveguide wavelength locker and the laser. The controller generates a laser control signal based on the error signal that adjusts the first wavelength. The waveguide wavelength locker can alternately include first and second spaced gratings, Mach-Zehnder interferometers with different asymmetries, passive waveguide(s), and combinations thereof. The laser is mounted on a first temperature controlled package and the waveguide wavelength locker is mounted on the first temperature controlled package.

摘要： An optical amplifier with a flattened wideband response is obtained by coupling counter-propagating pumping energy into an optical waveguide to cause Raman amplification in the optical waveguide, and by reflecting an amplified signal received from the optical waveguide into an output waveguide using a reflector having a spectral characteristic that is complementary to the spectral gain characteristic of the Raman amplification.

摘要： An electrostatically controlled cantilever apparatus for continuous tuning of the resonance wavelength of a Fabry-Perot cavity is disclosed. A resonant cavity is formed between two distributed Bragg reflector (DBR) mirrors each composed of multiple DBR layers. One such layer is replaced with a layer which has been fully oxidized except for a small aperture. This layer provides both optical and current confinement which allows for low threshold currents and high output power.
