Ga. Fish et al., COMPACT, 4 X 4 INGAASP-INP OPTICAL CROSSCONNECT WITH A SCALEABLE ARCHITECTURE, IEEE photonics technology letters, 10(9), 1998, pp. 1256-1258
An InP-InGaAsP 4 x 4 optical crossconnect occupying only 2 x 2 mm(2) w
as demonstrated by combining 16 1 x 2 optically amplified suppressed i
nterference switches (OASIS) in a square array architecture. On/off ra
tios of 33 +/- 4 dB were measured for a majority of these elements and
fiber-to-fiber insertion loss of 3 dB was obtained using additional o
n-chip amplification stages.
