Various optical components may be fabricated using micro-ring resonators. Polymer material can be used for fabrication of micro-ring resonators. There are several advantages using polymers for the fabrication of micro-resonators. First the required refractive index contrast to achieve negligible radiation loss for a micro-resonator with a radius of 10 /spl mu/m is available in polymers. Second it is very easy to fabricate three dimensional photonic integrated circuits This is essential for vertical coupling to the micro-resonators. Also various materials are available so that one can easily achieve phase matching condition by using different materials for the waveguide and microresonator. This opens the door to achieve very high Q resonators using polymer. In this paper we describe the design and fabrication of the first micro-resonator using polymer materials.","PeriodicalId":18008,"journal":{"name":"LEOS 2001. 14th Annual Meeting of the IEEE Lasers and Electro-Optics Society (Cat.

Chemically assisted ion beam etching (CAIBE) technique is commonly applied to this aim, as it allows for vertical sidewall etching combined with high etch rates. However, while on the GaAlAs/GaAs basis some quite convincing results were achieved (Unger et al., 1993), this seems not to be the case for the InGaAsP/InP laser devices to the same extent. Published results were obtained either at low temperature etching (5/spl deg/C) with IBr/sub 3/ as a chemical component (Eisele et al., 1996), or at higher temperatures (250-300/spl deg/C) with Cl/sub 2/ using multilayer masks or thick (700 nm) SiO/sub 2/ (Youtsey et al., 1994; Dzioba et al., 1993; Tsang et al., 1999). In this paper we present, to our knowledge for the first time, results on ridge waveguide (RW) lasers with dry etched laser facets using a simple photoresist mask, without any additional treatment after the lithographic exposure. We demonstrate that the fabricated devices show identical characteristics to those of lasers with cleaved facets.","PeriodicalId":18008,"journal":{"name":"LEOS 2001. 14th Annual Meeting of the IEEE Lasers and Electro-Optics Society (Cat.
