Very narrow spectral filters with multilayered grating-waveguide structures
Promising configurations for grating-waveguide structures are presented. In these structures, the grating layer, which is normally adjacent to the waveguide layer, is displaced by means of an intermediate layer, resulting in significant reduction of losses and weaker coupling. This leads to very narrow spectral bandwidths and high contrast ratios. Experimental results reveal that the spectral b...
متن کاملInverse-Gaussian apodized fiber Bragg grating for dual-wavelength lasing.
A fiber Bragg grating (FBG) with an inverse-Gaussian apodization function is proposed and fabricated. It is shown that such a FBG possesses dual-wavelength narrow transmission peaks and the wavelength spacing between the two peaks is easily controllable during fabrication. Incorporating such a FBG filter into a fiber laser with a linear cavity, we obtain stable dual-wavelength emission with 0.1...
متن کاملHybrid grating reflector with high reflectivity and broad bandwidth.
We suggest a new type of grating reflector denoted hybrid grating (HG) which shows large reflectivity in a broad wavelength range and has a structure suitable for realizing a vertical cavity laser with ultra-small modal volume. The properties of the grating reflector are investigated numerically and explained. The HG consists of an un-patterned III-V layer and a Si grating. The III-V layer has ...
متن کاملWaveguide-Type Optical Wavelength Filters
Optical communications by dense wavelength division multiplexing (DWDM or WDM), which uses a number of wavelengths and a signal on each wavelength channel for transmission, has made massive progress as a high-speed, high-capacity optical communication system for the Internet age. A crucial device in this kind of communication system is the optical wavelength filter used to separate out the wave...
متن کاملBandwidth analysis of waveguide grating coupler.
The bandwidth of planar waveguide grating couplers is theoretically investigated based on the rigorous grating theory. We observe that the bandwidth behavior is not only determined by the grating coupler intrinsic properties, but also affected by the fiber parameters such as position, beam waist and Numerical Aperture. The rigorous bandwidth formula is derived. By analyzing the formula, several...
