    Recommended

    The Thin-Film Lithium Niobate Ultra-High Bandwidth Intensity Modulator is a high-performance electro-optic conversion device independently developed by our company, with full proprietary intellectual property rights. The product is packaged using high-precision optical coupling and assembly techniques, achieving an electro-optic 3 dB bandwidth of up to 70 GHz. Compared with traditional bulk lithium niobate crystal modulators, this product features low half-wave voltage (Vπ), high stability, compact size, and thermal-optic bias control. It can be widely applied in digital optical communications, microwave photonics, backbone communication networks, and research projects in related communication fields.
