Temperature characteristics of silicon-polymer hybrid material photonic resonator

Abstract

This paper presents temperature sensitivity analysis of a silicon-polymer hybrid photonic micro-ring resonator. Photonic micro-ring resonators have hailed for their potential used in the next generation optical communications. However, like any other optical devices, temperature fluctuations alter the functionality of the micro-ring resonator. Hence, this paper provides a proposal for solution to minimize the temperature sensitive effect on the resonance characteristics. The temperature sensitivity effect of the pure silicon micro-ring resonaltor has been investigated. It is shown that the pure silicon micro-ring resonator is very sensitive to temperature. We added a negative thermo-optic polymer material with the positive thermo-optic silicon material to investigate the efeect of temperature sensitivity. Simulation tool Lumerical solution has been used to simulate the ring resonator. A polymer material of LFR is used to analyze the temperature effects. The hybrid composition of silicon-polymer were as 30%-70%, 40%-60%, 50%-50% and 60%-40% to investigate the temperature effect. The simulation was carried out using a ring size of 5 um, 10 um, 15 um and 20 um. The results show that the temperature insensitive ring resonator is possible with a 42% LFR polymer mixwd with 58% silicon.
