Method And Apparatus For Pulse Generation And Adaptive Pulse Generation For Optical Communications

US Patent:
7266307, Sep 4, 2007
Filed:
Aug 9, 2002
Appl. No.:
10/215036
Inventors:
Isaac Shpantzer - Bethesda MD, US
Israel Smilanski - Rockville MD, US
Jacob B. Khurgin - Baltimore MD, US
Vladimir Grigoryan - Elkridge MD, US
Pak Shing Cho - Gaithersburg MD, US
Nadejda Reingand - Baltimore MD, US
Guy Levy-Yurista - Tel Aviv, IL
Guoliang Li - North Potomac MD, US
International Classification:
H04B 10/00
H04B 10/04
US Classification:
398193, 398155, 398195, 398199
Abstract:
One embodiment of the invention relates to producing optical pulses for use on a transmission link. A light source is configured to produce an optical signal. A pulse generator is coupled to the light source. The pulse generator is configured to receive, for a first channel, the optical signal and a clock signal. The pulse generator is also configured to modify the optical signal based on the clock signal to produce an optical pulse having a predetermined pulse shape. The clock signal is associated with the predetermined pulse shape. The predetermined pulse shape being based on a transmission characteristic of the transmission link.

Method Of Making An Enhanced Coupling Strength Grating Having A Cover Layer

US Patent:
2019035, Nov 21, 2019
Filed:
Jul 25, 2019
Appl. No.:
16/522544
Inventors:
- Dallas TX, US
- Redwood Shores CA, US
Jay B. Kirk - Plano TX, US
Jin Yao - San Diego CA, US
Guoliang Li - San Diego CA, US
Xuezhe Zheng - San Diego CA, US
Ashok V. Krishnamoorthy - San Diego CA, US
International Classification:
G02B 6/34
G02B 6/132
G02B 6/136
Abstract:
The present invention includes an optical waveguide with a grating and a method of making the same for increasing the effectiveness of the grating. In one example, the grating is at least partially covered by a liner layer disposed on at least a portion of a grating; and a cover layer disposed on the liner layer, wherein a first material selected for the core and ridges and a second material selected for the liner layer are selected to provide a difference in the index of refraction between the first and second material that is sufficient to provide a contrast therebetween.
