Abstract

A temperature stabilized CMOS-compatible frequency comb based on an integrated optical micro-ring resonator is demonstrated. The instrument operates in the wavelength interval 1520-1600 nm with a wide free spectral range of 577 GHz. By embedding a highly sensitive “resistive thermal device” (RTD) on the surface of the chip to provide temperature feedback to the thermal electric cooler, the bench top unit achieves temperature stability of ~ 5:10⁷ over a 24 hour period with good power stability. Our approach reduces the cost and complexity of existing high precision frequency combs currently used in the fields of metrology, remote sensing and stellar spectroscopy where high stability is required for prolonged periods of time.
