- In this paper, we give an overview of recent results on switching of light in fibers with internal electrodes. Polarization rotation, nanosecond gating, and wavelength switching in fiber Bragg gratings and in long period gratings are discussed. Applications are exemplified in Q-switching fiber lasers and in RF-signal filtering.

- All-fiber optical switches based on fiber with electrodes exhibit transition times <10ns. The devices are monolithic and robust, they are simple and could potentially be manufactured at low cost. The insertion loss is extremely low and the devices are compatible with single mode fiber technology. Two types of switches are discussed, one based on polarization rotation, the other one relying on the wavelength shift of a fiber Bragg grating (FBG).

High-speed switching in fibres with electrodes

Konferensbidrag (refereegranskat)abstract
- Fibres with holes are provided with metal electrodes that fill the entire cross-section of the holes. Refractive index change and birefringence result from applying high current pulses for time intervals in the nanosecond range. High-speed polarization rotation and fibre Bragg grating wavelength tuning can be accomplished. Such electrically driven components are totally spliced with low insertion loss. They have no moving parts, are < 10 cm long and can be used in fibre laser cavities for Q-switching.

All-fiber single-pulse selection and nanosecond gating

- Two functions normally attributed to Pockels cells are performed with internal-electrode microstructured fiber components. Single-pulse selection out of a 100 MHz mode-locked pulse train is demonstrated using all-fiber nanosecond polarization rotation. Additionally, off-on-off gating with duration similar to 13 ns is achieved with a polarization rotator made out of a four-hole silicate fiber.

- FBGs were written in fiber with internal alloy electrodes. Nanosecond high current pulses cause metal expansion, increase birefringence and tune the gratings. High-speed wavelength switching was accomplished with potential use in Q-switching fiber lasers.

Nanosecond switching of fiber Bragg gratings

Tidskriftsartikel (refereegranskat)abstract
- A FBG was written in a two-hole fiber with internal alloy electrodes. Nanosecond high current pulses cause metal expansion, increase birefringence and tune the gratings with a response time of 29 ns. This short length, low loss, all-spliced high-speed wavelength switching devices described here has potential use in Q-switching fiber laser.
