A receiver and method for using the same to process optical signals is disclosed. The receiver includes an optical coupler and a polarization dependent beam splitter. The optical coupler combines an input signal and a local oscillator signal into a first combined signal. The optical coupler includes a polarization filter that operates on the local oscillator to provide a linearly polarized signal having a predetermined LO polarization direction.

An optical attenuator having a multi-mode waveguide segment and a perturbation element. An incident single-mode optical signal is converted to a multi-mode optical signal in the multi-mode waveguide segment. The optical attenuator couples incident light into higher order modes of the multi-mode waveguide segment resulting in attenuation of the incident optical signal.

Optical packaging assemblies and methods of making the same are described. In one aspect, an optical packaging assembly includes a package housing, a hermetically sealed optical device housing, and an optical fiber alignment assembly. The package housing includes an optical fiber feedthrough and a package electric feedthrough. One or more optical fibers extend through the optical fiber feedthrough. The hermetically sealed optical device housing is mounted within the package housing and includes an optical window and a device electric feedthrough that is electrically connected to the electric feedthrough of the package housing. At least one optical device is mounted within the hermetically sealed optical device housing in optical alignment with respect to the optical window. The optical fiber alignment assembly is mounted within the package housing and holds end portions of the one or more optical fibers in alignment for optical communication through the window of the hermetically sealed optical device housing.
