1.6T DR8 Thin-film Lithium Niobate Mach-Zehnder Modulator Chip
Series:
ORI-MZM-T-BW is the thermal tuning version, whose phase shift is tuned by micron heaters integrated on chip. Compared to traditional LN modulators, the heater version could maintain a lot more stable bias point throughout lifetime of the device. The device is a hermetic sealing package with internal optical power, which save more space size for the end user.
Highlights
● Based on cutting-edge thin-film Lithium Niobate (TFLN) technology;
● Low Vpi for driverless operation;
● Small formfactor
● Low insertion loss;
● Spot-size inverters integrated.
● Support single LD input or dual LD input.
● Ori-chip’s proprietary design, designed and fabricated by Ori-Chip.
