Thin-film Lithium Niobate MZ Modulator (IO)
Highlights
● State-of-art LNOI technology
● Low Vpi
● High Bandwidth
● High output power
● Small size: roughly 3cm long
● Internal Optical Source with TEC
Description
Based on state-of-art Lithium Niobate on insulator (LNOI) technology, this intensity modulator inherits most of the advantages of traditional lithium niobate modulators, and has a miniature form factor, low driving voltage and low loss.
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.
The low RIN laser source is also integrated in the package. Two MPD’s are included for power monitoring purpose. One PD is used to monitor the laser output power and the other is to monitor the MZ bias point.
