Researchers from the Department of Applied Physics at the University of Tsukuba demonstrated second-order nonlinear optical effects in diamonds by taking advantage of internal color center defects ...

A research group led by University of Tsukuba has observed the cooperative behavior of polaron quasiparticles formed by the collective interaction of electrons and lattice vibrations around color ...

Quantum photonic devices require efficient access to solid-state spin qubits serving as quantum memories or single-photon sources and nonlinearities. Additionally, they demand nonlinear and ...

Researchers showed that diamonds with color center defects can act as nonlinear optical materials for second-harmonic photon generation. This discovery can pave the way for completely light-based ...
