Abstract: An optoelectronic device includes a silicon interposer and an array of resonant cavity mesas. The array of resonant cavity mesas is monolithically integrated in a set of one or more epitaxial layers and flip-chip bonded to the silicon interposer. The array of resonant cavity mesas includes a first subset of resonant cavity mesas connected to a first subset of conductors of the silicon interposer and biased to a first electrical polarity, and a second subset of resonant cavity mesas connected to a second subset of conductors of the silicon interposer. The second subset of resonant cavity mesas provides electrostatic discharge (ESD) protection for the first subset of resonant cavity mesas.

Abstract: A laser assembly includes a set of one or more substrates having a first surface opposite a second surface. The set of one or more substrates defines a resonant cavity extension. The resonant cavity extension extends into the set of one or more substrates from an opening in the first surface. The laser assembly further includes a first reflector disposed within the resonant cavity extension and configured to reflect at least one wavelength of electromagnetic radiation received through the opening back through the opening; a laser having an active region configured to generate the at least one wavelength of electromagnetic radiation; and a second reflector. The active region is disposed in a resonant cavity extending between the first reflector and the second reflector. The resonant cavity includes the resonant cavity extension.
