TFLN Intensity Modulator (Integrated Light Source)
- High RF Bandwidth up-to 40 GHz
- Low half-wave voltage down-to 2V
- Low insertion loss down-to 4.5 dB
- Small device size
Attachment
The thin-film lithium niobate (TFLN) intensity modulator is an exceptional opto-electric converter device, which was developed in-house and showcased unparalleled performance. This device features thermal-optic bias control interface and is manufactured using advanced coupling and micro-electronic processes, and realizes high opto-electric conversion efficiency on TFLN. Compared to other commercial bulk lithium niobate-based modulators, our products provide superior characteristics on half-wave voltage, stability, and device size, significantly enhancing critical performance in digital optical communications and telecommunication networks.
