نویسندگان
چکیده
A novel bandwidth tunable bandpass filter based on a silicon microring-MZI structure is proposed and demonstrated. By thermally tuning the resonance offset between the two microring resonators, and adding the two drop transmissions together, the bandwidth of the microring-MZI filter can be easily linearly tuned with low in-band ripples. Key words—bandwidth tunable; thermal tunable; optical filter; microring; optical signal processing.

We propose and experimentally demonstrate a wavelength and bandwidth-tunable comb filter based on silicon Sagnac loop mirrors (SLMs) with Mach-Zehnder interferometer (MZI) couplers. By thermally tuning the MZI couplers in common and differential modes, the phase shift and reflectivity of the SLMs can be changed, respectively, leading to tunable wavelength and bandwidth of the comb filter. The f...

A silicon modulator with microring array assisted MZI is experimentally demonstrated on silicon-on-insulator wafer through CMOS-compatible process. The footprint of the whole modulator is about 600 μm(2). With forward-biased current-driven p-n junction, the 3-dB modulation bandwidth is ~2GHz. Furthermore, the impact of ambient temperature is minified with the help of MZI. Within temperature ran...

We propose and experimentally demonstrate a tunable fractional order photonic differentiator using an on-chip electrically tuned Mach-Zehnder interferometer (MZI) structure. The phase shift at the resonant frequency of the MZI varies when applying different voltages, which can implement the fractional differentiation. Due to the large 3-dB bandwidth of the MZI, the differentiator is expected to...
