To perform these functions, optical modules require high-precision optical signal generation and detection, which is where optoelectronic chips—including laser chips and photodetector chips—play a key role. These two types work hand in hand to enable data transmission through optical signals. Laser chips, or light-emitting chips, are the heart of optical communication systems. Optical modules are widely used in data centers, metropolitan area networks, long-haul telecom networks, and 5G backhaul. Why silicon photonics now? Here's an example: If a discrete module has eight 200G channels in one chip, it requires four EML lasers to run at 1. Optical chip, generally refers to the use of light waves (electromagnetic waves) as the carrier of information transmission or data calculation, relying on integrated optics or silicon-based optoelectronics medium optical waveguide to transmit guided-mode optical signals, the modulation of optical.
