We describe and demonstrate a new oscillator topology, the parametric feedback oscillator (PFO). The PFO paradigm is applicable to a wide variety of nanoscale devices and opens the possibility of new classes of oscillators employing innovative frequency-determining elements, such as nanoelectromechanical systems (NEMS), facilitating integration with circuitry and system-size reduction. We show ...

All-fiber optical parametric oscillator (FOPO) has received considerable attention throughout these years. In this paper, we review the basic theory—four wave mixing (FWM) in the optical fibers, which leads to the parametric amplification. Phase matching condition is then discussed, with emphasis on the phase matching near the zero dispersion wavelength. In the end, recent developments on FOPO ...

We report the experimental realization of a new type of optical parametric oscillator in which oscillation is achieved by polarization rotation in a linear retarder, followed by nonlinear polarization mixing. The mixing is performed by a type II degenerate parametric downconversion in a periodically poled KTP crystal pumped by a 1064 nm pulsed Nd:YAG pump. A single, linearly polarized beam, pre...

We report what is to our knowledge the first demonstration of a continuous-wave singly resonant optical parametric oscillator based on potassium titanyl phosphate. The pump source used is a single-frequency resonantly doubled Nd:YAG laser. By double passing the pump through the crystal, we achieved a minimum oscillation threshold of 1.4 W. With 3.2 W of incident pump power, a maximum 1.07 W of ...

We present a parametric resonance-based mass sensor, comprised of a single-crystal silicon micro-oscillator with sensitivity at the pico-gram (10 g) level when operating in air. This mass sensor detects mass change by measuring frequency shift at the boundary of the first order parametric resonance ‘tongue’. High sensitivity is achievable due to the sharp jump in amplitude caused by parametric ...

A type-II phase matched optical parametric oscillator is investigated for the generation of intensity correlated twin photon beams using potassium titanyl phosphate (KTP) as a nonlinear medium. The input pump source is a Kr'-ion laser at XP = 531nm with signal and idler twin photon beams at X,, = 1.06gm. Mirror and crystal losses were characterized for use in cavities of two-and three-piece con...

We report a femtosecond optical parametric oscillator (OPO) based on the nonlinear material BiB3O6. The OPO is synchronously pumped in the blue by the second harmonic of a Kerr-lens-mode-locked Ti:sapphire laser. It can provide wide and continuous tuning across the entire green-yellow-orange-red spectral range with a single crystal and a single set of mirrors. Using a 500 microm BiB3O6 crystal ...

Many models of supersymmetry breaking, in the context of either supergravity or superstring theories, predict the presence of particles with Planck-suppressed couplings and masses around the weak scale. These particles are generically called moduli. The excessive production of moduli in the early Universe jeopardizes the successful predictions of nucleosynthesis. In this paper we show that the ...
