Negative Group Delay and Superluminal Propagation: An Electronic Circuit Approach
M. Kitano, T. Nakanishi, K. Sugiyama
We present a simple electronic circuit which provides negative group delays for band-limited, base-band pulses. It is shown that large time advancement comparable to the pulse widt…

Generation of photon pairs using polarization-dependent two-photon absorption
T. Nakanishi, K. Sugiyama, M. Kitano
We propose a new method for generating photon pairs from coherent light using polarization-dependent two-photon absorption. We study the photon statistics of two orthogonally polar…
