Polymeric multi-channel bandpass filters in phase-shifted Bragg waveguide gratings by direct electron beam writing.
نویسندگان
چکیده
We apply direct electron beam writing to fabricate corrugated sidewall Bragg gratings in polymer waveguides and demonstrate multi-channel passband filters based on a phase-shifted design. Experimental results are compared with numerical fittings to analyze the impact of signal polarization and waveguide cladding material upon device performance.

Control of light transmission in laser-written phase-shifted Bragg grating couplers.
We demonstrate the fabrication by direct laser writing and the operation of a directional coupler containing Bragg gratings in each waveguide. We achieve high-precision control over the longitudinal shift between the gratings, which feature first-order Bragg resonance at telecommunication wavelengths. We observe fundamental differences between light transmission characteristics in couplers with...
متن کاملExperimental observation of coupling between physically separated planar waveguides utilising tilted Bragg grating structures
We demonstrate a novel optical device used to couple light from one channel waveguide to another 100 μm away. An investigation into the blaze angle of the tilted gratings used to couple light into the cladding modes is presented. Keywordstilted Bragg gratings; direct UV writing.
متن کاملWaveguide Bragg Gratings in Ormocer®s for Temperature Sensing
Embedded channel waveguide Bragg gratings are fabricated in the Ormocer® hybrid polymers OrmoComp®, OrmoCore, and OrmoClad by employing a single writing step technique based on phase mask technology and KrF excimer laser irradiation. All waveguide Bragg gratings exhibit well-defined reflection peaks within the telecom wavelengths range with peak heights of up to 35 dB and -3 dB-bandwidths of do...
متن کاملOptical waveguide filter fabricated by excimer laser irradiation
Ge-SiO2 thin films highly photosensitive to excimer laser light were deposited by plasma enhanced chemical vapor deposition. In this paper, the following two studies are reported: (1) Direct writing of the channel waveguide was successfully confirmed only by irradiation with excimer laser through a Cr mask pattern, which was previously coated on the slab waveguide by sputtering method. Bragg gr...
متن کاملOptical pulse compression based on nonlinear silicon waveguides and chirped Bragg gratings
Due to the growing demand for higher bandwidth, employing optical devices instead of electronic devices in data transmission systems has attracted much attention in recent years. Optical switches, modulators and wavelength converters are a few examples of the required optical devices. CMOS compatible fabrication of these devices, leads to much more growing of this technology. Optical pulse comp...
