Infrared Generation In Semiconductor Lasers

View page
US Patent:
6782020, Aug 24, 2004
Filed:
Sep 10, 2001
Appl. No.:
09/950458
Inventors:
Marlan O. Scully - Bryan TX
Alexey A. Belyanin - College Station TX
Vitaly V. Kocharovsky - College Station TX
Vladimir V. Kocharovsky - Nizny Novgorod, RU
Assignee:
The Texas AM University System - College Station TX
International Classification:
H01S 500
US Classification:
372 45, 372 4, 372 21, 372 39, 372 43
Abstract:
Infrared generation is disclosed. A first laser field having a first frequency associated with a first interband transition is generated. A second laser field having a second frequency associated with a second interband transition is generated. The generation of the first laser field occurs substantially simultaneously with the generation of the second laser field. A third laser field is generated from the first laser field and the second laser field. The third laser field has a third frequency associated with an intersubband transition. The third frequency is substantially equivalent to a difference between the second frequency and the first frequency.

Phase Matched Parametric Light Generation In Monolithically Integrated Intersubband Optical Devices

US Patent:
6940639, Sep 6, 2005
Filed:
Mar 29, 2004
Appl. No.:
10/812328
Inventors:
Alexey Belyanin - College Station TX, US
Alfred Yi Cho - Summit NJ, US
Claire F. Gmachl - Princeton NJ, US
Oana Malis - Chatham NJ, US
Arthur Mike Sergent - New Providence NJ, US
Deborah Lee Sivco - Warren NJ, US
Assignee:
Lucent Technologies Inc. - Murray Hill NJ
International Classification:
G02F001/39
G02B006/10
H01S005/34
US Classification:
359330, 372 44, 385122, 385131
Abstract:
An optical device comprises a cavity resonator and an intracavity ridge waveguide. The ridge waveguide includes a monolithically integrated intersubband core region and a nonlinear mixing region (NMR). In response to external pumping energy the core region generates laser light at a first frequency and in a first transverse mode. In response to the laser light the NMR generates parametric light at a second frequency and in a second transverse mode. For phase matching the effective-refractive-index-versus-ridge-width characteristics of the modes of the laser and the parametric light intersect one another at a phase matching width and so that, at greater widths, the effective refractive index of the mode of the higher frequency light is less than that of the lower frequency light. For true phase matching the width of the ridge is made to be essentially equal to the phase matching width.

Methods And Apparatus For Generating Terahertz Radiation

US Patent:
7974325, Jul 5, 2011
Filed:
Mar 14, 2008
Appl. No.:
12/450211
Inventors:
Mikhail A. Belkin - Austin TX, US
Federico Capasso - Cambridge MA, US
Alexey Belyanin - College Station TX, US
Assignee:
President and Fellows of Harvard College - Cambridge MA
The Texas A&M University System - College Station TX
Harvard University & Medical School - Boston MA
International Classification:
H01S 5/00
US Classification:
372 4601, 372 4501
Abstract:
Apparatus and methods for generating radiation via difference frequency generation (DFG). In one exemplary implementation, a quantum cascade laser (QCL) has a significant second-order nonlinear susceptibility (χ) integrated in an active region of the QCL. The QCL is configured to generate first radiation at a first frequency ω, second radiation at a second frequency ω, and third radiation at a third frequency ω=ω−ωbased on difference frequency generation (DFG) arising from the non-linear susceptibility. In one aspect, the QCL may be configured to generate appreciable THz radiation at room temperature.

Detecting Infrared Radiation

View page
US Patent:
6730910, May 4, 2004
Filed:
Oct 31, 2001
Appl. No.:
10/003655
Inventors:
Robert W. Boyd - Rochester NY
Clovis R. Haden - College Station TX
Marlan O. Scully - Bryan TX
Vitaly Kocharovsky - College Station TX
Alexey Belyanin - College Station TX
Assignee:
The Texas AM University System - College Station TX
International Classification:
G01J 500
US Classification:
2503381
Abstract:
According to one embodiment, detecting radiation includes receiving a first laser drive field at a cell comprising a medium having a number of states. The first laser drive field has a frequency approximately equivalent to a transition frequency between a first state and a second state. A second laser drive field having a frequency approximately equivalent to a transition frequency between the first state and a third state, and an infrared field having a frequency approximately equivalent to a transition frequency between the third state and a fourth state are received. The medium has a transition between the second state and the third state substantially forbidden to support optimal coherence on the transition between the second state and the third state. The infrared field is upconverted to generate a detectable field having a frequency approximately equivalent to a transition frequency between the second state and the fourth state.
