Abstract

A racetrack-based modulator of increased linearity for optical links is presented and analyzed. The modulator is referred to as FLAME - Finer Linearity Amplitude Modulation Element. Linearity is improved via the introduction of a Double Injection approach. Large spurious-free-dynamic-range (SFDR) of 132dB∗Hz4/5 can thus be theoretically obtained. The FLAME is studied for silicon photonics and requires small footprint size and low operation voltage, 2.5V. This makes the FLAME an appealing candidate for large scale integration in RF photonics. The optical structure of the modulator was fabricated and characterized in SOI platform. The results confirm the advantages of our newly introduced Double Injection method.
