System And Method For Laser Temperature Compensation

View page
US Patent:
7443894, Oct 28, 2008
Filed:
Apr 20, 2007
Appl. No.:
11/788639
Inventors:
Alfred Riddle - Milpitas CA, US
John Havard - Seattle WA, US
Assignee:
Finesse Solutions, LLC - Santa Clara CA
International Classification:
H01S 3/13
H01S 3/00
H01S 3/04
US Classification:
372 34, 372 29015, 372 3807
Abstract:
A method for compensating for changes in output power or wavelength of an optical source with temperature. Many optical sources have power and/or wavelength variations with temperature which can be compensated by open- or closed-loop methods if a method of accurately measuring the optical source temperature is available. The voltage across a semiconductor junction varies with temperature. Measuring the optical source power or wavelength variation with temperature and tracking the voltage across the semiconductor junction provides a means for compensating an instrument for temperature induced optical output power or wavelength variations. An important field of application is optical density or turbidity measurements in cellular media.

System And Method For Temperature Measurement

View page
US Patent:
8092084, Jan 10, 2012
Filed:
Jul 28, 2008
Appl. No.:
12/220816
Inventors:
Alfred Riddle - Milpitas CA, US
Anthony Sproul - San Jose CA, US
Assignee:
Finesse Solutions, LLC - San Joe CA
International Classification:
G01K 7/14
G01K 7/16
G01K 7/21
G01K 7/22
G01K 7/24
US Classification:
374185, 374171, 374173, 327513, 702130
Abstract:
A method for precision thermal measurement and control, especially for bioreactors, as well as the correction of temperature sensitive probes such as pH and dissolved oxygen. Typical control requirements are +/−0. 1 C. The thermal measurement circuit converts a sensor output to a high level voltage or current with great accuracy and provides noise immunity and sensor isolation. While digital outputs from sensor converters can have the greatest noise immunity, the noise associated with digital circuitry may contaminate low level sensor signals so in many cases an analog sensor converter is preferred because of low noise generation, especially if the converter is near the sensor. The circuit is low cost, reliable, generates minimal heat is immune to, and does not generate noise, and requires minimal calibration effort.

Multi-Tone Phase Modulation For Light Wave Communication System

View page
US Patent:
58284770, Oct 27, 1998
Filed:
Nov 16, 1995
Appl. No.:
8/559057
Inventors:
Alan C. Nilsson - Mountain View CA
Chien-Yu Kuo - Cupertino CA
Joseph Kleefeld - Palo Alto CA
Charles H. Gall - Newark CA
Alfred Nicholson Riddle - Milpitas CA
Harry Chou - San Jose CA
Assignee:
Harmonic Lightwaves, Inc. - Sunnyvale CA
International Classification:
H04B 1004
US Classification:
359181
Abstract:
An optical transmission system enables launching at least 17 dBm of optical power at 1550 nm wavelength into an e. g. 50 km long span of standard telecommunications single-mode optical fiber, without incurring unacceptable penalties from stimulated Brillouin scattering, damage to optical phase modulators from excessive drive power or thermal effects, or signal degradations caused by the SBS suppression. High frequency modulation of the laser drive current is combined with lower frequency modulation of the phase of the laser output light that is itself varied over a range of approximately 25 MHz. This two tone modulation raises the SBS threshold to greater than 17 dBm in the 1550 nm wavelength region when the laser has a line width less than 10 MHz, under cw operation. By thereby dividing the task of spectral partitioning between the laser and the phase modulator, the RF input power level to the phase modulator is manageable and the laser operates in a regime that does not cause clipping.

Ultraminiature 180 Degree Phase Shifter

View page
US Patent:
50457314, Sep 3, 1991
Filed:
Oct 27, 1989
Appl. No.:
7/427787
Inventors:
Alfred N. Riddle - Milpitas CA
Assignee:
Avantek, Inc. - Milpitas CA
International Classification:
H03L 700
H03K 5159
H01P 300
US Classification:
307511
Abstract:
A 180 degree ultraminiature phase shifter. Only two switching devices and very few passive circuit elements are required, thus allowing an extremely small and low loss device to be fabricated. When power is applied to switching devices, a low pass pi section low pass filter is realized which provides +90 degrees of phase shift. When power is absent from the switching devices, a T section high pass filter is realized which provides -90 degrees of phase shift.
