Mid-IR Optical Isolators
Jan 2013Innovation PhotonicsRequest Info
Quantum cascade lasers can be troubled by feedback. InnPho’s optical isolators prevent reflections (feedback) from returning back into the laser. Now in production are wavelength-tunable mid-IR optical isolators operating at center wavelengths of 4.5 µm, 8 µm and 10.6 µm. Typical transmission of ~90% and isolation of 500:1 to 1000:1.
