Porous carbon nanowire array for highly sensitive, biocompatible, reproducible surface-enhanced Raman spectroscopy
Nan Chen, Ting-Hui Xiao, Zhenyi Luo +5
Surface-enhanced Raman spectroscopy (SERS) is a powerful tool for vibrational spectroscopy as it provides several orders of magnitude higher sensitivity than inherently weak sponta…
Forward stimulated Brillouin scattering in silicon microring resonators
Yaojing Zhang, Liang Wang, Zhenzhou Cheng +1
Stimulated Brillouin scattering (SBS) has been demonstrated in silicon waveguides in recent years. However, due to the weak interaction between photons and acoustic phonons in thes…
Enhanced optical nonlinearities in air-cladding silicon pedestal waveguides
Yaojing Zhang, Zhenzhou Cheng, Yifei Yao +1
The third-order optical nonlinearity in optical waveguides has found applications in optical switching, optical wavelength conversion, optical frequency comb generation, and ultraf…
Polarization Dependent Loss and All-Optical Modulation in Graphene on Suspended Membrane Waveguides
Zhenzhou Cheng, Hon Ki Tsang, Xiaomu Wang +5
We observe a strong polarization dependent optical loss of in-plane light propagation in silicon waveguide due to the presence of graphene. Both transverse-electric (TE) and transv…
