4-dB quadrature squeezing with fiber-coupled PPLN ridge waveguide module
Naoto Takanashi, Takahiro Kashiwazaki, Takushi Kazama +4
We have developed an optical parametric amplification module for quadrature squeezing with input and output ports coupled with optical fibers for both fundamental and second harmon…
Wide-field SU(1,1) interferometer
G. Frascella, E. E. Mikhailov, N. Takanashi +3
An interferometer uses a sequence of two optical parametric amplifiers for achieving sub-shot-noise sensitivity to a phase shift introduced in between. We present t…
Generation and measurement of a squeezed vacuum up to 100 MHz at 1550 nm with a semi-monolithic optical parametric oscillator designed towards direct coupling with waveguide modules
Naoto Takanashi, Wataru Inokuchi, Takahiro Serikawa +1
We report generation and measurement of a squeezed vacuum from a semi-monolithic Fabry-Perot optical parametric oscillator (OPO) up to 100 MHz at 1550 nm. The output coupler of the…
