PURPOSE:To efficiently generate a second harmonic wave by constituting the end part on the side where a basic wave is made incident of a waveguide array consisting of plural pieces of optical waveguides and constituting the rear stage part of a Y-shaped optical waveguide group which joins the ...
CONSTITUTION:The optical second harmonic wave generating element is constituted by providing electrodes 1, 3 on the waveguide layer 2. The element is so formed that laser light of a wavelength lambda is projected to the waveguide from one end thereof and the light of 1/2.lambda wavelength is ...
Intense radiation in the terahertz (THz) frequency range can be generated by focusing of an ultrashort laser pulse composed of both a fundamental wave and its second-harmonic field into air, as reported previously by Cook et al. [Opt. Lett. 25, 1210 (2000)]. We identify a threshold for...
摘要: An analysis of the second harmonic amplitude modulation of an electromagnetic wave propagating through an acoustically disturbed plasma is given. On the basis of some numerical results it is concluded that this second harmonic modulation may be quite significant....
Resonantmetasurfaces are an attractive platform for enhancingthe nonlinear optical processes, such as second harmonic generation(SHG), since they can generate large local electromagnetic fieldswhile relaxing the phase-matching requirements. Here, we demonstratevisible range, continuous wave (CW) SHG by co...

For the case of the optical superlattice embedded in air, though we take polishing technology to reduce the reflection of the incident light, the conversion efficiency is also very low and the fundamental wave is mudulated. In order to increase the second harmonic generation conversion efficiency,...
