✦ Synopsis

Continuous tunable mid IR generation is analyzed by difference frequency generation (DFG) in an optical parametric oscillator (OPO). The periodically poled KTiOPO 4 (PPKTP) crystals are used for DFG of position tuning, temperature tuning and noncollinear angle tuning. Using position tuning and temperature tuning of OPO, signal wavelength tuning of DFG is also analyzed. The tuning curves, the tolerances and the walk-off angles of these tuning methods are given. The noncollinear angle tuning in combination with the temperature tuning is a better tuning method. Its advantages include wider tunable range and rapid tunability.

## Abstract A frequency‐tunable terahertz (THz)‐frequency electromagnetic‐pulses generation method is proposed based on an optical Fabry–Perot (FP) microresonator with variable birefringence materials. At the output FP microcavity, polarization mode beat with high‐frequency can be achieved due to t

To realize a future high-speed and ultralargecapacity optical transmission, it is indispensable to analyze the ultrahigh-speed transmission characteristics of the entire system as well as functional circuits, devices and materials comprising the system. Evaluation of such a transmission characterist
