Appl. No.:

12/757712

Peter G. Wigley - Corning NY, US

International Classification:

H04B 10/00
G02F 1/01

US Classification:

398159, 359260, 359238

Abstract:

A tunable dispersion compensator (TDC) is tuned from a first dispersion setpoint to a second dispersion setpoint while maintaining continuity of the dispersion. The dispersion tuning follows a pre-determined trajectory in the time domain, so that continuity of the optical dispersion across the channel optical bandwidth is maintained while minimizing all other TDC-induced optical impairments during a tuning period

Appl. No.:

12/924218

Inventors:

Aaron J. Zilkie - Painted Post NY, US

International Classification:

G01B 9/02

US Classification:

356454

Abstract:

A temperature-tuned dielectric-slab-etalon scanning spectrometer that is low cost and simple to fabricate uses cascaded etalon modules, each module comprising a Fabry-Perot (FP) etalon having a relatively small Free Spectral Range (FSR), with at least two modules provided with a temperature control. According to the invention, the multiple FP modules produce Vernier tuning control. In these devices, the tuning temperature range is typically less than 10 C., and the required slab thickness may be less than 1 mm. This reduces fabrication and material requirements, and results in lower device cost and improved reliability.

International Classification:

G02F 1/13

US Classification:

349198

Abstract:

A voltage-tuned optical filter that is low cost and simple to fabricate uses cascaded etalon modules, each module comprising a liquid crystal etalon, such as a Fabry-Perot etalon, having a relatively small Free Spectral Range (FSR). At least two of the modules are provided with a voltage control to enable Vernier tuning control. For a given overall scan, the voltage-tuned optical filter may operate with reduced voltage ranges for each liquid crystal etalon.

International Classification:

G02B 6/26

Abstract:

An optical out-coupler unit for out-coupling light from a waveguide, comprising a substrate having a planar top surface, a waveguide arranged on the top surface of the substrate and having a facet, a reflective surface, wherein the reflective surface is arranged spaced apart from the facet and opposing the facet, wherein the reflective surface is inclined with respect to a normal to the top surface of the substrate by more than 45. The optical out-coupler may be part of a photonic integrated chip (PIC).

International Classification:

H01L 33/00
H01L 31/18

Abstract:

A method of preparing a device coupon for a micro-transfer printing process from a multi-layered stack located on a device wafer substrate. The multi-layered stack comprises a plurality of semiconductor layers. The method comprises steps of: (a) etching the multi-layered stack to form a multi-layered device coupon, including an optical component; and (b) etching a semiconductor layer of the multi-layered device coupon to form one or more tethers, said tethers securing the multi-layered device coupon to one or more supports.
