초록
We present cost effective 2×2 silicon nitride Mach-Zehnder interferometric thermo-optic switches with 1 mm-length phase shifter. Devices were fabricated on a bulk silicon wafer with CMOS compatible process. The footprint was 0.7 mm2. For the device designed for {\\lambda}~1310nm, we demonstrated 26.8-dB crosstalk, 0.23-dB insertion loss, and 17.25-μ switching speed at {\\lambda}~ 1325.8nm. Similarly, {\\lambda}~ 1550 nm device showed the 24.7-dB crosstalk, 0.48-dB insertion loss, and 17.48-μ switching speed at {\\lambda} ~ 1550.8nm. The measured operating power was 55.6 and 64.4 mW at {\\lambda} ~1325.8 nm and {\\lambda} ~ 1550.8 nm, respectively.
