They are of great interest with respect to future photonic devices. The ...
Due to the large number of passes through the crystal, low insertion losses and high homogeneity are essen- tial for conversion efficiency. The special highest quality material selected by SHG efficiency mapping of each crystal, fine surface polishing and dual band AR coat- ings with very ...
Optical silicon is generally lightly doped (5 to 40 ohm cm) for best transmission above 10 microns, and doping is usually boron (P-type) and phosphorus (N-type). After doping silicon has a further pass band: 30 to 100 microns which is effective only in very high resistivity uncompensated...
Moreover, band engineering paves the way for wider applications of perovskite single crystals. 3.2. Optical properties Perovskite single crystals exhibit different PL characteristics under different circumstances. It is demonstrated that the single crystals exhibit a weak PL intensity and short lifetime ...
