International media recently reported that scientists at the Harvard John A. K. Howe School of Engineering and Applied Sciences, in collaboration with the Technical University of Vienna, have developed a new semiconductor laser. This laser utilizes a simple crystal design and enables efficient, reliable, and versatile wavelength transmission.
Tunable lasers are crucial for technologies such as high-speed communications, medical diagnostics, and pipeline safety. However, existing laser technology faces numerous challenges. For example, lasers tuned to long wavelengths typically have low monochromatic accuracy and require complex and expensive moving mechanical parts. This new invention could replace many existing collimated lasers with more compact and cost-effective packages.
Box Optronics offers tunable C-band and L-band lasers that deliver continuous power at 96 wavelengths in the C-band and 128 wavelengths in the L-band (ITU-T standard wavelengths, 50 GHz wavelength range).
