ine-azulene, for which there is considerable spectroscopic data, but the scheme is general enough to allow a wide choice of D and A pairs. We present results based on this pair, in which, for the first time, an all optical half-adder and full-adder logic circuits are implemented.

Walther Rathenau laser was achieved based on the optical resonances induced by two local phase shifts in the DFB structure. A stable microwave signal at . with a –3-dB width of 9 kHz and a long-term frequency stability of ± 2. 5 MHz was created via the heterodyne photo-detection of the two laser wavelengths. Intera

process is gaining more focus towards wastewater treatment for complete mineralization of the pollutants under mild temperature and pressure requirements. A photocatalyst must have good light UV–Vis light absorption capability for better photocatalytic performance. Recently, a process of dye decolou

Walther Rathenau silicon substrates. Uniform surface-relief Bragg gratings were patterned by laser-interference lithography and etched into the SiO. top cladding. The maximum grating reflectivity exceeded 99 %. Monolithic DFB cavities with Q-factors of up to 1. 35 × 10. were realized. The Er.3+-doped DFB laser deli
