Method Of Fabricating Optical Device Using Multiple Sacrificial Spacer Layers

Patent Identifier: 
RE45084

The present invention is a method of fabricating an optical device using multiple sacrificial spacer layers. The first step in this process is to fabricate the underlying base structure and deposit an optical structure thereon. A facet is then created at the ends of the optical structure and alternating sacrificial and intermediate layers are fabricated on the device.

Phoniton Systems, Devices, And Methods

Patent Identifier: 
9397293

An artificial composite object combines a quantum of sound with a matter excitation. A phonon in a confinement structure containing the matter excites it from an initial state to an excited state corresponding to a frequency of the phonon. Relaxation of the matter back to the initial state emits a phonon of the same frequency into the confinement structure.

Photoacoustic Joulemeter Utilizing Beam Deflection Technique

Patent Identifier: 
8711342

A joulemeter is capable of non-destructively measuring multiple characteristics of a laser beam. The joulemeter comprises a series of parallel probe beams, which are directed though a transparent media adjacent to an absorbing media that the tested beams pass through. Arrays of optical sensors or a chirp sensor are used to intercept and measure deflections the probe beams.
