We report on the static and dynamic performance of high-power and high-modulation-speed 1060-nm distributed Bragg reflector (DBR) lasers for green-light emission by second-harmonic generation.… (More)
We report a high kink-free facet power of 852 mW and a high single-wavelength facet power of 350 mW for 1060-nm raised-ridge Fabry-Perot (FP) and distributed-feedback (DFB) lasers, respectively.
To achieve good overall performance for wireless communication systems, it is essential to have good channel estimation performance. In this paper, based on a practical MIMO (Multiple-Input… (More)
Vector OFDM (Orthogonal Frequency Division Multiplexing) for single transmit antenna systems is a general transmission scheme, where OFDM and SC-FDE (Single-Carrier Frequency Domain Equalization) can… (More)
We report highly reliable 1060-nm DBR lasers with a single-wavelength output power larger than 350 mW and a failure rate as low as 3.2 kFITs at a heat-sink temperature of 25degC and a gain current of… (More)
We report highly reliable 1060-nm DBR semiconductor lasers after aging the gain section and DBR-section heater for up to 24000 and 11000 hrs, respectively, at various high-stress conditions.
We fabricated 1060-nm DBR lasers with 480-mW output power and integrated micro heaters. A 20-nm discrete wavelength tuning using Bragg-section heater alone and a 1-nm continuous tuning using both… (More)
Coherence-collapse operation of a Bragg grating stabilized thick-quantum-well laser diode yields 975-nm wavelength emission with >40 dB side-mode-suppression ratio, 1% power variation, and… (More)
Reliability tests on packaged ultraviolet light-emitting diodes (LEDs) in the ultraviolet-C (UVC) range (<; 280 nm) were performed under various temperatures and currents. At higher case temperature,… (More)
Vector Orthogonal Frequency Division Multiplexing (V-OFDM) for single transmit antenna systems is a generalization of OFDM where Single-Carrier Frequency Domain Equalization (SC-FDE) and OFDM are… (More)
