Wafer characterisation
One challenge in Terahertz spectroscopy is the independent determination of refractive index and geometrical thickness of a given sample. This can be solved for semiconductor…
Gas cell
Gas molecules have intra-molecular movements such as vibrational, rotational and translational motions, which absorbs energy in the THz frequency range. Another reason to use THz radiation…

Y-DFB laser:
This laser features a Y-shaped resonator with a shared gain segment (combiner segment) and two separate gain segments for selective feedback at 1536 nm and 1544 nm with top-etched slots…
Monolithic dual mode lasers
Monolithic dual-mode lasers are beneficial for THz systems due to their compact, integrated design, which enables stable and coherent THz signal generation through…
Y-DBR laser:
The Y-DBR laser is a micro-integrated dual-wavelength master oscillator power amplifier (MOPA) designed and fabricated by our cooperation partner Ferdinand-Braun Institute. The laser…
