Epi-wafers for QCLs

A close-up of a scientific optical setup with red laser beams passing through and reflecting off various lenses and mirrors mounted on a perforated metal surface.

High-precision, scalable MOCVD growth of Quantum Cascade Laser epiwafers are supported by advanced calibration methods and extensive characterization capabilities.A gold-colored electronic component with a rectangular body, multiple metal pins extending from one side, and a circular opening on the front, mounted on a base with four screw holes.

QCL epi-wafers refer to epitaxially grown semiconductor structures tailored for the fabrication of Quantum Cascade Lasers (QCLs)—advanced light sources capable of emitting in the mid- to far-infrared spectrum through intersubband transitions within quantum well structures. Due to their wavelength tunability, high power, and narrow spectral output, QCLs are essential components in many high-performance systems across industries such as environmental monitoring, medical diagnostics, industrial process control, aerospace, defense, and scientific research.
