6941080, Sep 6, 2005
Filed:
Jul 15, 2002
Appl. No.:
10/195662
Inventors:
Bryon Lynn Kasper - San Marino CA, US
Eva Peral - Pasadena CA, US
Johannes G. Ransijn - Wyomissing Hills PA, US
Assignee:
TriQuint Technology Holding Co. - Hillsboro OR
International Classification:
H04B010/04
US Classification:
398186, 398182, 398183, 398192, 398193, 398194, 398195, 372 33, 372 34, 372 35, 372 36, 372 38, 372 29
Abstract:
An optical transmitter includes a laser driver capable of receiving data and applying the data to drive a laser diode over a transmission line having first and second ends. The first end of the transmission line is coupled to an output of the laser driver. A first terminal of an amplifier is coupled to the second end of the transmission line. A second terminal of the amplifier is coupled to the laser diode. The signal amplitude applied at the first terminal controls optical output amplitude of the laser diode.

Opto-Electronic To-Package And Method For Laser

US Patent:
7011455, Mar 14, 2006
Filed:
Jun 19, 2003
Appl. No.:
10/465276
Inventors:
Xin Simon Luo - Baldwin Park CA, US
Bryon Lynn Kasper - San Marino CA, US
Eva Peral - Pasadena CA, US
Matthew Swass - Tujunga CA, US
Assignee:
Emcore Corporation - Somerset NJ
International Classification:
G02B 6/42
US Classification:
385 88, 385 93
Abstract:
An optical interface between an optical fiber and a laser is provided. The optical fiber has a core and an end. The optical interface includes a mirror that is capable of receiving an optical output of the laser and of reflecting the optical output to the end of the optical fiber such that a chief ray of the optical output is incident on the core of the optical fiber. The optical interface also includes a lens located such that the chief ray of the optical output traverses a center of the lens. Such optical interface may be used in a transmitter optical subassembly (TOSA) having a vertical TO package for un-cooled lasers.

Distortion Cancellation Circuitry For Optical Receivers

US Patent:
7596326, Sep 29, 2009
Filed:
Oct 27, 2005
Appl. No.:
11/262077
Inventors:
Eva Peral - Altadena CA, US
Bryon L. Kasper - San Marino CA, US
Assignee:
Emcore Corporation - Albuquerque NM
International Classification:
H04B 10/06
US Classification:
398211, 398210
Abstract:
An optical receiver having a photodetector coupled to an external optical fiber for receiving an optical communications signal and converting it into an electrical signal; an RF amplifier coupled to the electrical output of the photodetector and generating an output signal with distortion; and a post-distortion circuit connected to the output of the RF amplifier for canceling the distortion in the output signal produced by the RF amplifier.

In-Line Distortion Cancellation Circuits For Linearization Of Electronic And Optical Signals With Phase And Frequency Adjustment

US Patent:
7634198, Dec 15, 2009
Filed:
Jun 21, 2006
Appl. No.:
11/472194
Inventors:
Eva Peral - Altadena CA, US
Assignee:
Emcore Corporation - Albuquerque NM
International Classification:
H04B 10/18
H04B 10/00
H03F 1/34
H03F 3/08
H03F 5/00
US Classification:
398159, 398140, 398158, 398163, 327317, 330296
Abstract:
A distortion circuit is provided for correcting the distortion from a nonlinear circuit element by generating a frequency dependent signal having a sign opposite to the distortion signal produced by the nonlinear circuit and substantially the same magnitude. The distortion circuit includes an input signal and a first nonlinear device coupled to the input signal for generating a first signal and where the first nonlinear device has a first bias level. Also included is a second nonlinear device different from same first nonlinear device and coupled to the first nonlinear device for modifying the first signal to produce an output second signal, the second nonlinear device having a second bias level. A bias control means is provided for adjusting the first and said second bias levels so that the magnitude, phase and frequency of the output second signal can be adjusted.
