Abstract
An integrated silicon nitride resonator is proposed as an ultracompact
source of bright single-mode quadrature squeezed light at 850 nm.
Optical properties of the device are investigated and tailored through
numerical simulations, with particular attention paid to loss associated
with interfacing the device. An asymmetric double layer stack waveguide
geometry with inverse vertical tapers is proposed for efficient and robust
fibre-chip coupling, yielding a simulated total loss of -0.75 dB/facet. We
assess the feasibility of the device through a full quantum noise analysis
and derive the output squeezing spectrum for intra-cavity pump self-phase
modulation. Subject to standard material loss and detection efficiencies, we
find that the device holds promises for generating substantial quantum noise
squeezing over a bandwidth exceeding 1 GHz. In the low-propagation loss
regime, approximately -6 dB squeezing is predicted for a pump power of
only 75 mW.
