Abstract

Amplitude-squeezed light with intensity fluctuations 29% below the standard quantum limit (SQL) is produced from a pump-suppressed room-temperature semiconductor laser, corresponding to 41% below the SQL after correction for detection efficiency. Excess noise, which degrades the observed squeezing, appears to be associated with the presence of weak longitudinal side modes.

Photocurrent noise power spectrum from the laser (trace A) and the LED (trace B) when the differential amplifier added the detector photocurrents at 28 MHz. Squeezing is indicated by the laser noise dropping below the LED noise (SQL) at certain frequencies.
