Each waveguide stack can include a plurality of waveguides, where a first waveguide stack may be associated with a first subcolor of each of three different colors, and a second waveguide stack may be associated with a second subcolor of each of the three different colors. For example, the ...
We report picosecond all-optical switching in optical communication band using a LiNbO 3 waveguide quasi-phase matched second-harmonic generation/difference-frequency generation device. Analysis based on the beam propagation method showed that 1 ps switching with 3.1% efficiency is feasible with 10 W ...
摘要: Data fidelity is inspected for the first time for wavelength-converted RZ TDM 80- and 160-Gb/s data using four-wave mixing in a silicon waveguide. Open eye diagrams and error-free operation is shown for demultiplexed 10-Gb/s tributaries....
The emission wavelength of a light source is the vacuum wavelength (or wavelength in air) of the emitted light. The Bragg wavelength of a Bragg mirror is the vacuum wavelength for which that mirror has the highest reflectivity. The cut-off wavelength of a waveguide is the vacuum wavelength ab...
19. OPG in the LWIR region from theχ(2)waveguide device is experimentally exploited, driven at a central wavelength of 2.4 μm. The generated idler pulse has an octave spectrum spanning from 5 to 11 μm. Owing to the inherently efficient quadratic nonlinear response, waveguide-enhanced ...
Optical coherence tomography apparatus using optical-waveguide structure which reduces pulse width of low-coherence light In an optical coherence tomography apparatus: low-coherence light from a light source is split into signal light and reference light; at least one of the frequencies of the signal...
ASE wavelength control and tuning in a wedge waveguide were realized. The tuning range of the waveguide can reach as much as 30 nm. This method can be applied to wide-range wavelength tuning in solid-state tunable lasers.关键词: Lasers, solid-state Waveguides ...
14A. This method is advantageous because it can obtain a multiplexing ability if the sensing system is implemented using a multi-channel filter, such as an arrayed waveguide grating (Okabe et al., 2007). However, the disadvantage of this system is that its sensitivity is relatively low because...

A waveguide is a rectangular or circular pipe, usually made of copper, that confines and guides very high-frequency electromagnetic waves between two locations. Compared with coaxial cable, it has a very low attenuation at microwave frequencies, which is its main advantage. Its main disadvantages ...
