Frequency-tuned semiconductor whispering-gallery-mode laser (λ = 2.35 µm) operating at room temperature

Frequency tuning in a whispering gallery mode (WGM) semiconductor laser (λ = 2.35 µm) with a sector (half-disk) cavity has been studied. Pumping by current pulses with a duration of up to 1.2 µs is accompanied by smooth tuning of the main WGM toward longer wavelengths by 30 Å at room temperature, wh...

Description
Summary:	Frequency tuning in a whispering gallery mode (WGM) semiconductor laser (λ = 2.35 µm) with a sector (half-disk) cavity has been studied. Pumping by current pulses with a duration of up to 1.2 µs is accompanied by smooth tuning of the main WGM toward longer wavelengths by 30 Å at room temperature, which is 1.4 times the intermode distance.
