Analysis of optical crosstalk within optoelectronic integrated circuits including lasers and photodetectors
Abstract
Optical crosstalk from a 1.3 mu m laser to a 1.55 mu m photodiode on a single InP substrate, and its suppression within 1.3 mu m/1.5 mu m Y-junction transceiver OEICs, has been analyzed experimentally. The results indicate that the optical crosstalk suppression is limited by the accumulated light in the OEIC substrate coming mainly from the spontaneous emission of the integrated laser and from stray light at the laser waveguide butt joint interface. For OEICs, integrating lasers and photodetectors, the achievable optical intra-chip crosstalk at present will be in the range of 30-40 dB at the required small die dimensions.
