Intra-Mode Squeezing in the Quantum Optical Frequency Comb

This thesis demonstrates the presence of two-mode squeezing within a broadband squeezed light field generated by an OPO pumped just below threshold. Past experiments have confirmed the existence of this phenomenon, but we have demonstrated the technique over an approximately 1 MHz frequency range, with a highly tunable measurement technique. Through the use of a two-frequency local oscillator generated by a double sideband modulation of an EOM, we are able to measure many two-mode squeezed fields within the spectrum of one OPO output mode. Such a technique has great potential for observing larger, more densely packed optical cluster states, which could be used to construct a quantum computer.
