In this paper, we experimentally present a novel, all-optical spectral efficient vertical-cavity surface-emitting laser- (VCSEL-) based technique for routing and spectrum assignment in optical networks. Exploiting all optical VCSEL-to-VCSEL injection to attain cross gain modulation, the optical transmitter is optimized for optical transmission paths to assure quality of service by overcoming blockage for differentiated bandwidth demands during network congestion incidences. A 10 Gbps directly modulated 1549 nm master VCSEL is optically injected into the 1549 nm side modes of a 1550 nm slave VCSEL. The Shannon limit is considered for higher transmission rates with the problem decomposed into degraded routing and spectrum assignment and chromatic dispersion in the optical transmission link penalties. In this work, the proposed technique achieved a 1.3 dB penalty for transmission over a 25 km G.655 nonzero dispersion-shifted single-mode optical fibre, a value within the transmission media and optical system characteristics of 3 dB as recommended by the International Telecommunication Union-Telecommunication (ITU-T). The number of transceivers, switches, and optical transmission links in the network was reduced, increasing the number of satisfied bandwidth requests, thus optimizing the spectral resource utilization.

The extraordinary optical transmission (EOT) and diffraction through nanoslit composed of two finite-width metallic films with periodic or aperiodic sub-wavelength corrugation were studied. The transmitted spectra were calculated and compared, and the numerical results showed that two transmission peaks exist for the periodic corrugation, while for aperiodic one the transmission peaks are split into seven, corresponding to their different periods and couplings. Further investigation indicated that resonant wavelength of Surface Plasmon Polaritons (SPPs) determined by the nanoslit can be distinguished. It is expected that this investigation will provide useful information for further designing various nano-scaled optical filters and wavelength division multiplexer (WDM) in the next all optical network (AON).
