4000-enhancement of difference frequency generation in a mode-matching metamaterial

Photon entanglement signatures in difference-frequency-generation.

In response to quantum optical fields, pairs of molecules generate coherent nonlinear spectroscopy signals. Homodyne signals are given by sums over terms each being a product of Liouville space pathways of the pair of molecules times the corresponding optical field correlation function. For classical fields all field correlation functions may be factorized and become identical products of field...

Difference-frequency generation in AgGaS2 by using single-mode diode-laser pump sources.

Enhancement of sum frequency generation near the photonic band gap edge under the quasiphase matching conditions.

We analyze theoretically and study experimentally the mechanisms of enhancement of the sum frequency and second harmonic generation in a finite one-dimensional photonic band gap structure with second order nonlinearity under Bragg diffraction conditions. It is shown that, near the photonic band gap edge, the efficiency of conversion in sum frequency and second harmonic generation processes can ...

Tuning extension of a Difference-Frequency generation up to 100 nm using V-shaped external-cavity for the pump laser

In this research, tunability of a commercial diode laser has extended to about more than ± 11 nm using a V-shaped external-cavity fabricated around the laser. Although under normal condition it can be tuned up to about ± 4 nm just by changing its temperature and injection current. Such modified diode laser has then used in a difference-frequency generation (DFG) experimental setup as pump sourc...
