Effect of D2 outdiffusion on direct writing of optical waveguides

Research output: Contribution to journalJournal articleResearchpeer-review


It is shown that the performance of UV written waveguides can be influenced strongly by the outdiffusion of molecular deuterium during fabrication. By cooling the sample to -33 °C, the time available for UV writing may be increased to > 10 h, compared to ~15 min at room temperature.
