Abstract

Defect-mediated subbandgap absorption is observed in ion-implanted silicon-on-oxide waveguides that experience a rapid thermal annealing at 1075°C. With this effect, general carrier-depletion silicon modulators exhibit the capability of optical power monitoring. Responsivity is measured to be 22mA/W for a 3 mm long Mach–Zehnder modulator of 2×1018cm3 doping concentration at 7.1V bias voltage and 5.9mA/W for a ring modulator of 1×1018cm3 doping concentration at 10V bias voltage. The former is used to demonstrate data detection of up to 35Gbits/s.
