From: 110 GHz, 110 mW hybrid silicon-lithium niobate Mach-Zehnder modulator
(a) The measured optical transmission of the asymmetric hybrid-bonded Si/LN MZM with no modulation signal applied. The asymmetric path-length difference gives an FSR of 2.3 nm, and an average ER of 28 dB over 50 nm. (b) The measured \(V_\pi L\) of the hybrid MZM (\(L_\mathrm {ps} = 0.5\) cm) as a function of driving trapezoidal signal frequency. (c) A schematic block diagram of the quasi-CW high power electro-optic response measurement setup. Active RF multipliers were used for generating \(f>\) 50 GHz.
