摘要：

A remarkable improvement of external efficiency is achieved in double-heterojunction GaAs-GaAlAs superluminescent diodes (d.h. s.l.d.s) by application of antireflective coatings on the front face. The external differential quantum efficiency of 750–1500 µm long s.l.d.s increased from 1·2% to 4·5% (n.a. = 0·7) after coating the front face with a quarter-wavelength silicon-monoxide film. © 1979, The Institution of Electrical Engineers.
