A 40-GHz mode-locked fiber-ring laser based on an optically controlled modulator is presented and analyzed in detail. The modulator is a monolithic InGaAsP-InP Mach-Zehnder interferometer with integrated semiconductor optical amplifiers, which allows

We present a new technique for the efficient and simple production of amplitude-squeezed light with high coherent excitation, using a frequency doubler, in which only the fundamental wave is resonantly enhanced. Our theory predicts up to nearly 90% s

The concept of a doubly resonant frequency doubler can be used for a variety of experiments concerning both classical phenomena like efficient frequency doubling at low power levels and quantum effects like squeezed states of light or Quantum Non Dem

We report on a beam of squeezed light with considerable power (3.2 mW). 52% noise reduction in the fundamental mode is observed by second-harmonic generation in a monolithic resonator with active frequency stabilization.

We measure fourth-order interference occurring when energy-entangled photon pairs are launched into opposite ports of a single-mode-fibre interferometer. The resulting 90% coincidence fringe visibility is limited only by dispersion and polarisation a

We have measured the intensity fluctuations of the second-harmonic mode generated in a MgO:LiNbO3 external monolithic cavity pumped by a Nd:YAG laser. The cavity has mirror coatings for both the fundamental and the second-harmonic mode. We scan the c
