Wavelength-tunable amplitude-squeezed light from a room-temperature quantum-well laser.

We have observed amplitude noise levels as much as 1.8 dB below the Standard quantum limit in the light generated by an external-cavity-stabilized index-guided quantum-well laser operating at room temperature. The measured amplitude noise remains more than 1.5 dB below the Standard quantum limit as the lasing wavelength of this system is tuned from 831 to 841 nm.
