External-cavity wavelength tunable laser with an electro-optic deflector
A near-IR tunable external-cavity laser that uses an electro-optic deflector and a reflection grating as a tunable filter is demonstrated. The deflector is an electronically reconfigurable nonpixelated nematic liquid-crystal device. By controlling the voltage applied to the electro-optic deflector,...

| Zusammenfassung: | A near-IR tunable external-cavity laser that uses an electro-optic deflector and a reflection grating as a tunable filter is demonstrated. The deflector is an electronically reconfigurable nonpixelated nematic liquid-crystal device. By controlling the voltage applied to the electro-optic deflector, a tuning range of 12 nm and a side-mode suppression higher than 30 dB are obtained. |
