Folded Intensity Modulator with Ultra-low Vπ


Highlights 

● State-of-art LNOI technology

● Low Vpi ~2V

● High Bandwidth  

● Low Insertion Loss

● Small size: roughly 2.8cm long

 

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. 

We have two versions for this product, ORI-MZM-OT-BW is the thermal tuning version, whose phase shift is tuned by micron heaters integrated on chip. ORI-MZM-OV-BW is the voltage tuning version. Compared to traditional LN modulators, the heater version could maintain a lot more stable bias point throughout lifetime of the device. 

Please note that for ORI-MZM-OV-BW version, the RF input must be AC coupled, and can sustain the voltage applied on the DC port.
