Award List:

Pump Laser Diode Module

Award Year / Program / Phase:
2007 / SBIR / Phase I
Award Amount:
$99,999.00
Agency / Branch:
DOD / USAF
Principal Investigator:
Sabine Freisem, President
Abstract:
Experimental and theoretical evidence indicate that charge localization through a quantum dot active region can significantly increase pump laser diode performance by reducing threshold current density and internal loss. Because of its charge localization and lower operating current density, quantum… More

Compact Quantum Dot Mode-Locked Lasers for Arbitrary Waveform Generation

Award Year / Program / Phase:
2007 / SBIR / Phase I
Award Amount:
$100,000.00
Agency / Branch:
DOD / USAF
Principal Investigator:
Sabine Freisem, President
Abstract:
We propose to research and develop a new type of quantum dot (QD) mode-locked laser based on new active region and cavity designs. The cavity design will use a low loss QD/waveguide active region combined with index confinement through selective oxidation to enable cavity lengths greater than 1.5 cm… More

Vertical Cavity Surface-Emitting Laser (VCSEL) pumps for Reduced Eye Hazard Wavelength High Energy Fiber Lasers

Award Year / Program / Phase:
2008 / SBIR / Phase I
Award Amount:
$69,999.00
Agency / Branch:
DOD / ARMY
Principal Investigator:
Sabine Freisem, President
Abstract:
This SBIR proposal is to develop a new high power VCSEL array that can achieve higher efficiency and higher brightness than existing technology, suitable for pumping eye-safe fiber lasers. The technology uses a lithographically defined VCSEL process to achieve dense integration and reduce the diode… More

Compact Quantum Dot Mode-Locked Lasers for Arbitrary Waveform Generation

Award Year / Program / Phase:
2008 / SBIR / Phase II
Award Amount:
$749,983.00
Agency / Branch:
DOD / USAF
Principal Investigator:
Sabine Freisem, President
Abstract:
The proposed Phase II effort will extend the Phase I results to use new quantum dot laser diode designs based on increased cavity size and low internal optical loss to increase pulse energy over existing demonstrations. An integrated optical amplifier will be developed based on the same quantum dot… More

High-Power Semiconductor Laser in the 3.0- to 3.5-um Spectral Range

Award Year / Program / Phase:
2012 / STTR / Phase I
Award Amount:
$80,000.00
Agency / Branch:
DOD / NAVY
Principal Investigator:
Guowei Zhao, Research Scientist – (321) 274-7596
Research Institution:
UCF/CREOL
RI Contact:
Arlisia Potter
Abstract:
High quality laser materials based on InP, InGaAs, InAlGaAs, and InAs are proposed to develope high power 3 to 3.5 m diode lasers. An adiabatically broadened amplifying section is proposed to reach high power with high beam quality. The active material uses strained layer epitaxy to rely only on… More

Epitaxial growth for facet passivation of high power diode lasers

Award Year / Program / Phase:
2012 / SBIR / Phase I
Award Amount:
$100,000.00
Agency:
DOD
Principal Investigator:
Sabine Freisem, Senior Research Scientist – (407) 929-6675
Abstract:
A new facet coating material for high power diode lasers will be developed that reduces interface states at the cleaved facet and increases facet cooling. The facet coating is expected to be more robust and lead to increased power and brightness in high power diode lasers, bars and stacks. The facet… More

Quantum Dot Gain Material for High Reliability, Radiation-Hard Laser Diode Pump

Award Year / Program / Phase:
2012 / SBIR / Phase I
Award Amount:
$150,000.00
Agency:
DOD
Principal Investigator:
Sabine Freisem, Senior Research Scientist – (407) 929-6675
Abstract:
ABSTRACT: A new active material will be developed and tested to improve reliability for space applications. Recent improvement in facet reliability reveals that bulk failure mechanisms could limit laser diodes used in space. Radiation-induced defects are expected to occur in the bulk of the laser… More

Tactical Engagement Simulation System (TESS) Improved Laser Encoding and Decoding

Award Year / Program / Phase:
2013 / SBIR / Phase I

Agency / Branch:
DOD / ARMY
Principal Investigator:
Sabine Freisem, Senior Research Scientist – (407) 929-6675
Abstract:
A new approach to the Army Tactical Engagement Simulation System (TESS) is proposed to increase the link reliability, increase range, and increase the amount of data that can be transferred. The new technology uses both laser sources and detectors with improved propagation properties that meet… More
