Latest Patents
Zeshan Chang's latest patents include an optical transmitter and an optical modulation method. This optical transmitter features a wavelength selector and multiple modulator groups, each containing modulators with different operating wavelengths. The wavelength selector is designed to obtain a first beam from a multi-wavelength light source and generate a second beam that includes selected wavelengths from the first beam. A modulator within the modulator groups is responsible for modulating data onto a wavelength in the second beam.
Another notable patent is for an optical module, data center system, and data transmission method. This optical module comprises a first and second downlink port, a directional coupler, an optical attenuator, and two photodiodes (PDs). The directional coupler receives a downlink optical signal, while the second PD measures the power value. If this value exceeds a predetermined threshold, the optical attenuator adjusts the power of the optical signal passing through the second downlink port. The first PD converts the downlink optical signal into an electrical signal.
