J. Cross et al., A SINGLE-FIBER BIDIRECTIONAL OPTICAL LINK USING COLOCATED EMITTERS AND DETECTORS, IEEE photonics technology letters, 8(10), 1996, pp. 1385-1387
This letter reports the bonding of a small, thin-film GaAs-based emitt
er onto a larger silicon detector to realize spatial colocation of the
emitter and detector, These colocated devices enable single fiber bid
irectional communication between the two analog/digital silicon circui
ts that contain the emitter/detector pairs, Bidirectional communicatio
n between two of these circuits is demonstrated with a single plastic
optical fiber.
