Abstract: | A linear electrooptic coefficient of 0.3 pm/V is induced in a germanosilicate fiber by thermal/electric-field poling. Reducing the fiber thickness by simple mechanical polishing following the poling, leads to a half-wave drive voltage of only 75 V for a 12-cm active length with no measurable linear optical loss in the fiber. The induced linear electrooptic coefficient shows no decay at room temperature for over four months, and only a 10% decay after heating to 90/spl deg/C for 1000 h. |
