Interaction between a Waveguide Mode and an Absorptive Medium
Hadi Amarloo, Safieddin Safavi-Naeini
Absorption spectroscopy studies the absorption of electromagnetic wave in a material sample under test. The interacting electromagnetic wave can be propagating in free space or in…
Experimental Characterization of Ultrafast, Tunable and Broadband Optical Kerr Nonlinearity in Graphene
Siddharatha Thakur, Behrooz Semnani, Safieddin Safavi-Naeini +1
In this study we systematically measure the near-infrared spectral dependence, the sub-picosecond temporal evolution and pulse-width dependence of the effective Kerr coefficient ($…
A Fundamental Limit on Propagation Loss of Waveguides with Subwavelength Mode Size
Amir Arbabi, Ehsan Arbabi, Safieddin Safavi-Naeini
A fundamental trade-off relation between the cross sectional confinement and propagation length of an arbitrary mode of a general waveguide is presented. This limit is a generaliza…
Signal Recovery in Pulsed Terahertz Integrated Circuits
Abdorreza Heidari, Mohammad Neshat, Daryoosh Saeedkia +1
In this article, a time-domain calibration procedure is proposed for pulsed Terahertz Integrated Circuits (TIC) used in on-chip applications, where the conventional calibration met…
