A switch module includes a switch integrated circuit (IC), a photonic integrated circuit (PIC), and a planar lightwave circuit (PLC). The PIC may include a plurality of light sources, an optical splitter, and a plurality of modulators. A dual MEMS may be used to align lens arrays, which may be used to couple light from the PIC to the PLC.

Optical module for terabit switch

A directly driven laser includes multiple contacts, with at least one of the contacts for injecting current into the laser such that the laser reaches at least a lasing threshold and at least one of the contacts for providing a data signal to the laser. In some embodiments a differential data signal is effectively provided to a front and a rear section of the laser, while lasing threshold current is provided to a central portion of the laser.

Semiconductor laser device and circuit for and method of driving same

A widely tunable laser is described where a compound semiconductor gain chip is coupled to a waveguide filter fabricated on silicon. The filter has two resonators with different free-spectral-ranges, such that Vernier tuning between the filters can be used to provide a single wavelength of light feedback into the gain chip, where the wavelength is adjustable over a wide range. The coupling between the gain chip and the filter is realized through a microlens whose position can be adjusted using micromechanics and locked in place.
