High speed and low power optical phased array
WebAug 5, 2024 · Both thermo-optic (TO) and electro-optic (EO) phase shifters are applied in OPA widely [ 22, 23, 24, 25, 26, 27, 28, 29, 30 ]. Low loss can be obtained in TO shifters, while high power consumption and poor bandwidth follow. WebHere, the I ON and I OFF were extracted at V G = (high V T +low V T)/2.Two wake-up pulses of ±6.5 V, 500 µs were applied prior to pretesting for stable operations due to increased trap densities. At V write = 6.5 V with t pulse of 1 µs, a ratio of I ON to I OFF (I ON /I OFF) is larger than 20.At t pulse of 5 µs, the MW and the I ON /I OFF were ≈0.4 V and 200, respectively.
