	1	Athermal 4-channel (de-)multiplexer in silicon nitride fabricated at low temperature显示文摘We have designed and realized an athermal 4-channel wavelength(de-)multiplexer in silicon nitride(Si N).Minimized thermal sensitivity is achieved in a wide wavelength range by using wide and narrow waveguides with low and different thermal-optic coefficients in the two arms of Mach–Zehnder interferometers(MZIs). The Si N core layer and Si O2 cladding layers are deposited by a low-temperature plasma-enhanced chemical vapor deposition process. The fabricated MZI filter exhibits a thermal sensitivity within 2.0 pm∕°C in a wavelength range of 55 nm to near 1300 nm. Then, an athermal(de-)multiplexer based on cascaded MZIs has been demonstrated with a crosstalk ≤-22 d B and a thermal sensitivity <4.8 pm∕°C for all four channels, reduced by 77% compared to a conventional Si N(de-)multiplexer. Owing to the passive operation and compatibility with the CMOS backend process, our devices have potential applications in 3 D integration of photonics and electronics.
