The thermo-optic coefficient dn/dT of silicon was measured at 1550 nm in the wide temperature range from 5 K to 300 K. For this purpose an interferometric measurement scheme was applied using the silicon sample as a Fabry-Perot etalon. The high resolution of this setup revealed a thermo-optic coefficient as low as 10−8 K−1 at 5 K. The presented results show an excellent agreement with former measurements above 30 K including a value of dn/dT=1.8×10−4 K−1 at 300 K.
