Semiconductor lasers and optical amplifiers for optical communication

Laser DFB (Distributed Feedback )

Single-mode laser incorporating a network that creates a continuous coupling between the forward and return waves.

WDM (Wavelength Division Multiplexing )

The technique of passing several signals of different wavelengths over a single optical fiber to increase the fiber transmission rate.

PIC (Photonic Integrated Circuits )

Photonic circuits integrating several elements for transmission, reception, etc. functionality.

SOA (Semiconductor Optical Amplifier )

Semiconductor optical amplifier for amplifying an optical signal or for processing an optical signal (wavelength conversion, etc.).
