Quantum key distribution and single photon detection are the key technologies of quantum secure communication.

A spectrometer is an optical instrument that separates polychromatic light into a spectrum.

One of the most promising applications of quantum microwave photonics technology is the detection of extremely weak microwave/RF signals.

Microwave optical technology has become a powerful field, combining the advantages of optical and microwave technology in signal processing, communication

The process of loading information onto the laser is called modulation, and the device that performs this process is called a modulator.

the components of a simple photonic integrated circuit: laser, optical reuse and demultiplexing device, photodetector and modulator.

Today let's take a look at OFC2024 photodetectors, which mainly include GeSi PD/APD, InP SOA-PD, and UTC-PD.

Photodetector is a device that converts optical signal into electrical signal, ‌ its structure and variety

Before examining various forms of photodetectors, the characteristic parameters of the operating performance of optical signal photodetectors are summarized.

The development of optical communication technology and information technology is complementary to each other
