    • A semiconductor-based optical amplifier/attenuator is disclosed. An apparatus according to aspects of the present invention includes an optical waveguide disposed in semiconductor material. A first optical beam having a first wavelength is to be directed through the optical waveguide. The optical waveguide is optically coupled to receive a pump optical beam having a pump wavelength. The pump optical beam also has a power level sufficient to amplify the first optical beam via stimulated Raman scattering (SRS) in the optical waveguide. A diode structure is disposed in the optical waveguide. The diode structure coupled is to be selectively biased to selectively control free carrier lifetimes of the free carriers in the optical waveguide. This enables to selective amplification or attenuation of the first optical beam output from the optical waveguide.

    • Apparatuses for depolarizing light are disclosed. A disclosed passive optical depolarizer for depolarizing a polarized light source includes a waveguide and a first microresonator. The waveguide has a first birefringence. The first microresonator has a second birefringence different from the first birefringence and is evanescently coupled to the waveguide. A disclosed optical amplifier includes a substrate layer, a light source formed over the substrate layer, a waveguide formed over the substrate layer, and a first microresonator formed over the substrate layer. The light source is arranged to emit light from an output. The light has a degree of polarization greater than zero. The waveguide has a first birefringence and an input optically coupled to the output of the light source. The first microresonator has a second birefringence different than the first birefringence and is evanescently coupled to the waveguide.
