Emerging free-space optical communications applications require high power optical amplifiers (HPOAs) designed to differing requirements: wavelength band, modulation, polarization, and environment.
New OCT systems demand higher resolution using broadband SLDs. This paper presents a new class of SLDs based on chirped multilayered quantum dots to achieve broad spectral widths.
Gaussian shaped picosecond pulses as short as 62 psec have been obtained from an array of 10 phase coupled multi-quantum well GaAs lasers.
Semi-insulating blocked planar buried-heterostructure (SIPBH) lasers grown entirely by atmospheric-OMVPE had current thresholds as low as 20 mA and differential quantum efficiencies> 20% at 1.3
We present the design and the performance of a monolithically integrated master oscillator power amplifier at 1.5 μm.
We report on the design and characterization of uni-traveling-carrier photodiodes (UTC-PDs) achieving simultaneously high speed (ges 20 GHz), high responsivity (0.83 A/W), and high saturation curre
1300 nm InAs quantum dot narrow ridge superluminescent diodes have reached a high power of 70 mW/facet under CW operation, together with a broad spectral width of 80 nm.
High Power Optical Amplifiers (HPOAs) are key components in high-bandwidth, free-space communication systems.
1.32 mum InAs quantum dot narrow ridge lasers have reached a record single spatial mode optical power of 130 mW/facet under CW operation.
A new experimental method has been developed to probe ion/molecule reactions at gas pressures up to 0.1 torr.
