Paper Abstract

We propose the detection of magneto-optic signals using an external cavity laser diode suitable for constructing a small optical head. A magneto-optic medium is used as one of the cavity mirrors. This method is based on detecting the frequency-shift signal, instead of the conventional amplitude-modulated signal, and is expected to raise the signal-to-noise-ratio.
