Odd waveguide mode quasi-phase matching with angled and staggered gratings.
نویسندگان
چکیده
Angled and staggered gratings are used for quasi-phase matching of antisymmetric TM(10) modes in periodically poled lithium niobate waveguides with high efficiency. Control of the symmetry of the nonlinear coefficient d adds a new degree of freedom in the choice of which waveguide modes will interact in a quasi-phase-matched device.

Grating-assisted phase-matched second-harmonic generation from a polymer waveguide.
Diffraction gratings can be used to achieve phase matching between the fundamental modes of a slab or confined waveguide. Compared with the usual techniques such as quasi-, Cerenkov, and intermodal phase matching, the matching method used here involves spatial harmonics of the guided electromagnetic field that are generated by the corrugated grating. This grating acts simultaneously as a linear...
متن کاملEfficiency pedestal in quasi-phase-matching devices with random duty-cycle errors.
It is shown that random duty-cycle errors in quasi-phase-matching (QPM) nonlinear optical devices enhance the efficiency of processes far from the QPM peak. An analytical theory is shown to agree well with numerical solutions of second-harmonic generation (SHG) in disordered QPM gratings. The measured efficiency of 1550 nm band SHG in a periodically poled lithium niobate (PPLN) waveguide away f...
متن کاملQuasi-group-velocity matching using integrated-optic structures.
We propose a device to compensate for group-velocity mismatch (GVM) effects that limit the efficiency-bandwidth product in nonlinear frequency-mixing devices. Integrated wavelength-dependent delay lines are introduced periodically in a waveguide containing a series of quasi-phase-matching (QPM) gratings. Appropriate choice of the time delays can compensate for GVM. We have demonstrated a two-st...
متن کاملQuasi phase matching in GaAs--AlAs superlattice waveguides through bandgap tuning by use of quantum-well intermixing.
We report the observation of second-harmonic generation by type I quasi phase matching in a GaAs-AlAs superlattice waveguide. Quasi phase matching was achieved through modulation of the nonlinear coefficient chi((2))(zxy), which we realized by periodically tuning the superlattice bandgap. Second-harmonic generation was demonstrated for fundamental wavelengths from 1480 to 1520 nm, from the thir...
متن کاملNumerical analysis of nonuniform Bragg gratings
The characteristics of guided waves scattered by nonuniform Bragg waveguide gratings are systematically investigated by using a staircase approximation, which is a combination of the building blocks of the multimode network theory and a rigorous mode-matching procedure. The bent dielectric waveguides, periodically with Bragg gratings of rectangular profile and chirped waveguide gratings, are ta...
