Realization of a pump/signal duplexer using periodically segmented waveguide in integrated optics on glass
Abstract
Each integrated optics technology has his own advantages, well specific for different application<br />domains. For example, LiNbO3 substrates are widely used in electro-optic devices while III-V semiconductors<br />are very useful for optical sources. The integration of heterogeneous optical functions<br />and materials is consequently a difficult task. For example, for integrated optics by ion-exchange<br />on glass, substrates used for active and passive devices are different and incompatible. To address<br />this problem, the concept and the fabrication of the hybrid structure have been studied at IMEP<br />laboratory. This structure is composed by an active glass layer reported by molecular bonding on<br />a passive glass substrate with an ion exchanged waveguide. The hybrid structure represents an<br />attractive solution to fabricate an active amplifying waveguide on a passive substrate, but related<br />interfacing devices should be developed to be compatible with the hybridization techniques. In<br />this context, we study the realization of a pump/signal duplexer working on the 980 nm/1550 nm<br />range using a segmented asymmetric Y junction. At first, after analyzing the working principles of<br />the asymmetric junction, a detailed theoretical and experimental study of segmented waveguides<br />is presented. Then, the segmented asymmetric Y junction is studied theoretically and experimentally,<br />leading us to obtain a demultiplexer with (26 ± 1) dB of isolation at the l = 980 nm pump<br />wavelength, with (2.8±0.1) dB of insertion losses. For the signal, isolation rises from (9.7±0.1) dB<br />at ! = 1500 nm up to (15±0.1) dB at l = 1600 nm while insertion losses are between (3.1±0.1) dB<br />and (3.5 ± 0.1) dB in this spectral band. Perspectives of this work include an optimization of<br />performances and the integration with an hybrid structure in order to fabricate a monolithically<br />integrated optical amplifier.
