We present the first chip-scale “integrated optical driver” (IOD) that can interrogate with a sensing coil to realize an interferometric optical gyroscope. The chip comprises a light source, three photodiodes, two phase modulators and two 3-dB couplers within an area of 4.5 mm2. This allows for a significant reduction in size, weight, power consumption and cost of optical gyroscopes.
