Title:
COMPACT OPTICAL TRANSCEIVER
Document Type and Number:
WIPO Patent Application WO/2020/031478
Kind Code:
A1
Abstract:
[Problem] To provide a compact optical transistor. [Solution] An optical transistor which: includes a first substrate 3, a vertical-cavity surface-emitting laser (VCSEL) array 5 provided on the surface of the first substrate 3, and a first multicore fiber (MCF) 7 which is adhered to the rear surface of the first substrate at a position corresponding to the VCSEL array 5, wherein the first substrate 3 is a semiconductor substrate through which light emitted by the VCSEL array 5 passes; and also includes a second substrate 13, a photodetector (PD) array 15 provided on the surface of the second substrate, and a second multicore fiber (MCF) 17 adhered to the rear surface of the second substrate at a position corresponding to the PD array, wherein the second substrate 13 is a semiconductor substrate through which light which is incident on the PD array 15 passes.
