摘要:

Lead silicate glass sputtered onto GaAs‐AlGaAs injection lasers facets can yield optical coatings with near‐perfect linear‐expansion matching or refractive‐index matching by adjusting the PbO : SiO2ratio. Half‐wave coatings increase the lasing threshold by less than 5&percent;, while quarter‐wave coatings allow a large increase in power output for less than a 30&percent; increase in lasing threshold.
