We experimentally and numerically characterize stable and unstable μm-particle trapping in a dual-beam fiber-optical trap. We find that reducing the fiber separation leads to increasing restoring forces when the ratio of refractive indices approaches 1.005.
We report on polarization and reflectivity effects in FOPO output coupling. Polarization-based output coupling improves output power. Linear polarization and output coupling of 0.35 to 0.48 yields optimum output power with the current setup.
We show improvement in relative intensity noise (RIN) for a fiber optical parametric oscillator (FOPO) as a function of input power and of wavelength, an attractive alternative to supercontinuum (SC) for nonlinear optical microscopy.
We demonstrate identical and reversal relations between temporal pulse shapes and their spectrum envelopes through ultrashort optical parametric processes in the picosecond and femtosecond regimes.
We experimentally demonstrate and theoretically explore a spectral imaging system where two spectral sidebands produced through an optical parametric process always have reversed spectral profiles with respect to the center frequency of the pump.
We demonstrate a dual-beam fiber trap for optically stretching lipid vesicles encapsulated with poly(ethylene glycol) polymer solution. Vesicle deformations exhibit ranges of linear and non-linear response for applied peak stresses of ∼7–60 mN/m2.
We describe a 230 nm tunable fiber optical parametric oscillator (FOPO) using an 8 ps pump laser. The FOPO generates 2-4 ps pulses with conversion efficiency as high as 20%. The output spectrum exhibits power and synchronization-dependent broadening.
Pulse propagation simulations of fiber-optical parametric oscillators reveal an interesting interplay between spectral filtering, synchronization delay, and pump power. Our analysis implies that generation of sub-20-fs pulses is possible.
Sub-50 fs pulses with linear chirp at 969.4nm are generated using a synchronously-pumped fiber optical parametric oscillator where the suitable fiber length is chosen to compensate the dispersion from optical components inside of the cavity.
Sub-50 fs pulses at 940 nm having linear chirp are generated using a synchronously-pumped fiber optical parametric oscillator where the fiber length is chosen to compensate for dispersion from optical components inside of the cavity.
We present a systematic study of microstructure fibers reduced in size in order to tailor the group-velocity dispersion (GVD). The analysis includes taper recipes, GVD measurements, SEM images, and subsequent fiber optical parametric oscillator performance.
This letter presents an optically controlled, continuously tunable, dispersionless optical delay element in fiber based on a selective wavelength converter using a periodically poled lithium-niobate waveguide with two-pump configuration, dispersion-compensated fiber, and a dispersion compensator. Optical phase information is preserved in this technique, and there is no fundamental limitation on pulsewidth...
