Methods and apparatus for isolating a modulation region of an external modulator that has a semiconductor waveguide structure that comprises at least one integral isolation region.

Waveguide absorption modulator with integral optical isolator

An electro-optical signal translator, signal translator design features, methods of fabrication, alignment techniques and alignment apparatus that utilize, with the exception of output optical fiber to transmitter module coupling, passive assembly techniques that are compatible with assembly line operations to produce high performance electro-optical signal translators.

High speed electro-optical signal translator

A waveguide type electro-absorptive optical modulator that resists damage to its input facet and methods for minimizing or eliminating optical and electrical damage to the input facet of waveguide type electro-absorptive modulator by fabrication of an electrically isolated region in the modulator's waveguide proximate the input facet by forming an ion implantation region in at least one waveguide confinement rib proximate the input facet, a signal contact end on the at least one rib that is recessed from the plane of the input facet, or both.
