Integrated electro-optical modulator in the mid-IR spectral range
Spectroscopy sensing in the mid-infrared (mid-IR) range (2−20 μm wavelength) is an unambiguous way to detect and quantify small traces of environmental and toxic vapors. However, current mid-IR devices are often based on a free-space configuration, thus becoming bulky …

Silicon phase and intensity modulators for flat frequency comb generation
References Optical frequency combs are an essential tool in many fields. To generate them, it is possible to exploit silicon photonics phase and amplitude modulators. In this work we numerically investigate the performance of such devices for the generation …

Metamaterial engineered silicon photonic coupler for whispering gallery mode microsphere and disk resonators
Optical microresonators with high quality factors are key in photonic circuits requiring fine spectral filtering or resonant storage of optical power. Silicon (Si) photonics provides high-performance optoelectronic circuits but yields planar Si microresonators with rather low quality factors (Q …
