A system with a deformable membrane for speckle mitigation. In some embodiments, the system includes a laser for producing laser light; a photodetector for detecting the laser light after interaction of the laser light with a sample; and a silicon deformable membrane, for modulating the phase of the laser light.

Deformable membrane for speckle mitigation

A Mach-Zehnder waveguide modulator. In some embodiments, the Mach-Zehnder waveguide modulator includes a first arm including a first optical waveguide, and a second arm including a second optical waveguide. The first optical waveguide includes a junction, and the Mach-Zehnder waveguide modulator further includes a plurality of electrodes for providing a bias across the junction to enable control of the phase of light travelling through the junction.

Waveguide modulator structures

A modulator. In some embodiments, the modulator includes a portion of an optical waveguide, the waveguide including a rib extending upwards from a surrounding slab. The rib may have a first sidewall, and a second sidewall parallel to the first sidewall. The rib may include a first region of a first conductivity type, and a second region of a second conductivity type different from the first conductivity type. The second region may have a first portion parallel to and extending to the first sidewall, and a second portion parallel to the second sidewall. The first region may extend between the first portion of the second region and the second portion of the second region.
