In this work, we present a thermally tunable switch based on coupled micro-rings for on-chip optical interconnects. Such a device is designed to accomplish a 2.4 THz-large free-spectral range in the third telecom window (~1550nm) with 35 dB extinction ratio at 200 GHz away from the central frequency. The device is fabricated on a silicon-on-insulator platform with integrated Ti/TiN metal heaters. Optimizing the heater design, the power consumption for a full FSR tuning is minimized. The record value of 20 mW per FSR per ring is demonstrated with symmetric tuning..

Abstract
In this work, we present a thermally tunable switch based on coupled micro-rings for on-chip optical interconnects. Such a device is designed to accomplish a 2.4 THz-large free-spectral range in the third telecom window (~1550nm) with 35 dB extinction ratio at 200 GHz away from the central frequency. The device is fabricated on a silicon-on-insulator platform with integrated Ti/TiN metal heaters. Optimizing the heater design, the power consumption for a full FSR tuning is minimized. The record value of 20 mW per FSR per ring is demonstrated with symmetric tuning..I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione
