The laser bars additionally offer a special, single-quantum well structure that not only reduces the laser threshold
but also the semiconductor's absorption.
Other significant improvements offered by the SWQ products include a lower laser threshold
(up to 25% lower) and a 15% increase in operating efficiency, relative to conventional laser diodes.
Other features include: programmable amplitude and frequency modulation, low- noise read amplifier, programmable laser slope compensation DAC and programmable laser threshold
