Plugtech

We specialize in the development of advanced optical modulator bias controllers and fully customized optical modules. Our patented bias controllers are engineered for a wide range of modulators, including bulk LiNbO₃ and TFLN MZ, QPSK, and DP-QPSK devices. We offer both Electro-Optic (EO) and Thermo-Optic (TO) controllers, and provide tailored solutions to meet specific requirements for bias controllers and optical modulation modules. All our products are compact, user-friendly, and designed to operate seamlessly without the need for manual calibration.Dual sideband modulation is easily achieved with outstanding carrier suppression performance. System's overall effect is close to the performance limit of EOM.Plugtech was established at Hong Kong Polytechnic University in 2014. Since our inception, we have been dedicated to the development of Bias Controllers. We have successfully delivered over 7,000 controllers to laboratories and universities worldwide, including prestigious inst...
