In this paper, an experiment on tunable resonant cavity enhanced (RCE) phot
odetector with external cavity is reported. It is the first time to realize
a tunable RCE photodetector in China. A tuning range about 10 nm has been
obtained and further extension is expected. Corresponding theoretical analy
sis and discussions are presented. (C) 2000 Elsevier Science B.V. All right
