Abstract

A novel reconfigurable architecture based on slow-wave propagation in integrated optical ring resonators is proposed for the realization of variable optical delay lines. A continuously variable delay is achieved by combining a coarse discrete (digital) delay, provided by a coupled resonator slow-wave structure, with a fine continuous (analog) delay given by a cascaded ring-resonator phase-shifter. The reflective configuration of the structure enables a simple, accurate and robust tuning of the delay and provides a footprint reduction by a factor 2 with respect to conventional coupled resonator optical waveguides. Proof-of-concept devices realized in 4.4% silicon oxynitride waveguides and activated by a thermal control are discussed. Experimental results demonstrate, in both spectral and time domain, a continuously variable delay, from zero to 800 ps (2 bit fractional delay), on a 2.5 Gbit/s NRZ signal, with less than 8 dB insertion loss and less than 5 mm2 device footprint.

Fig. 2.

Photograph of (a) the SiON waveguide cross section and (b) the first rings of a SWDL realized with directly coupled ring resonators. The diameter of the rings is approximately 1.24 mm, corresponding to FSR=50 GHz.

Fig. 3.

(solid line) experimental and (dashed line) simulated (a) spectral intensity and (b) group delay characteristic of a SWDL with M=2 (blue), 3 (black) and 4 (red) tuned rings. The group delay, normalized to 2.5 Gbit/s NRZ pulse width (400 ps), is referred to as fractional delay.

Simulated pulse propagation (left column) and experimental eye pattern (right column) of a 2.5 Gbit/s NRZ optical signal delayed by a SWDL for an increasing number of rings tuned to resonance: M=0 (a), M=1 (b), M=2 (c) and M=3 (d). A total delay of 300 ps is induced without significant pulse distortion.
