Infrared‐to‐THz Detection and Spectroscopy with Whispering‐Gallery‐Mode Microresonators

Infrared‐to‐THz Detection and Spectroscopy with Whispering‐Gallery‐Mode Microresonators

A novel room‐temperature photodetector based on a silica‐microsphere optical resonator operating from the mid‐infrared to the terahertz spectral region is reported. The sensor relies on a free‐space visible laser whose frequency is locked to the center of a whispering‐gallery mode (WGM). The devised...
