Direct-write depressed cladding waveguide Bragg-gratings in ZBLAN glass
نویسندگان
چکیده
Strong waveguide Bragg-gratings (10 dB reflectivity) were fabricated by the directwrite technique in ZBLAN glass. Based on a depressed cladding, an array of 169 periodic and in phase modifications was placed inside the core.

Experimental 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 کاملUltrafast laser written active devices
Direct-write optical waveguide device fabrication is probably the most widely studied application of femtosecond laser micromachining in transparent dielectrics at the present time. Devices such as buried waveguides, power splitters, couplers, gratings, optical amplifiers and laser oscillators have all been demonstrated. This paper reviews the application of the femtosecond laser direct-write t...
متن کاملPolymeric multi-channel bandpass filters in phase-shifted Bragg waveguide gratings by direct electron beam writing.
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.
متن کاملDirect laser written waveguide-Bragg gratings in bulk fused silica.
Optical waveguides that incorporate Bragg gratings have been written in bulk fused silica by using the femtosecond laser direct-write method and without the need for lithography or ion-beam techniques. A single manufacturing process is used to create waveguide-Bragg grating reflectors for operation in the C band.
متن کاملEfficient 2.9 μm fluorozirconate glass waveguide chip laser.
We report a large mode-area holmium-doped ZBLAN waveguide laser operating at 2.9 μm, which was pumped by a 1150 nm diode laser. The laser is based on ultrafast laser inscribed depressed cladding waveguides fabricated in uniformly rare-earth-doped bulk glass. It has a threshold of 28 mW and produced up to 27 mW of output power at an internal slope efficiency of approximately 20%.
