An electro‐optic switch using total internal reflection by a ferroelectric liquid crystal is reported. The device has rise and fall times of about 150 μs, and causes the optical power in the output beam to be attenuated by a factor of 500 000 in the off state. It does not employ polarizers, and its operation is nearly independent of wavelength. The measurements here cover the 400–1600 nm band.
