Multi-dimensional carrierless amplitude phase (CAP) modulation attracts a lot interest in recent optical communications as an advanced modulation format with improved performance. In this study, we have demonstrated a multiband multi-dimensional CAP modulation scheme and investigated its applications in short reach optical communication systems. Similar to discrete multitone (DMT) technique, several independent bands can be loaded with different three dimensional carrierless amplitude phase (3D-CAP) signals in the proposed multiband 3-dimensional CAP system, offering improved tolerance to non-flat channels. Experimental transmission of 3D-CAP over SMF up to 45Gbps is also demonstrated.

Mid-Infrared (mid-IR) spectroscopy has been widely used to identify biomolecules. Due to the general poor interaction of mid-IR light with nanometric-scale molecules, the electro-optical properties of graphene resonant plasmons based device is exploited to demonstrate a tunable label-free protein sensor with high sensitivity. The confinement of graphene plasmons is much larger than that of the conventional metallic structure due to the two-dimensional nature of the collective oscillations of Dirac quasi-particles. The localized graphene plasmons can dynamically produce a high light overlap with nanometer size biomolecules, which plays an essential role in the resulted super sensitivity in the detection of the protein's permittivity. Furthermore, graphene plasmons merge optics with electronics which provide a unique capacity to control light in nanoscale. Tunable resonant spectra selectivity combined with the super ambient condition sensitivity promise the graphene plasmons based device exciting prospects in future nanoscale biosensing.

Due to the increasing network risk of large-scale disaster, it is important to protect failed requests for network operators. For the disaster survivable problem in an elastic optical datacenter networks with a bandwidth constraint, we formulate an integer linear program (ILP) for shared protection model. The algorithm utilizes the priori method to maximize the network throughput firstly, and then to minimize used spectrum resources. Unicast and anycast methods in shared protection are investigated. Simulation results show that both methods provide the same network throughput, but the anycast method can use much less spectrum resources than the unicast method.

We report the 1x4 optical splitters (OS's) for TE modes based on an air-hole type silicon photonic crystal selfcollimation (SC) effect ring resonator (SCRR). The OS has four beam splitters which are formed by changing the radii of the air holes. With the self-collimation effect and the radii we set for beam splitters, the light beam's propagation will be well controlled. Using the multiple-beam interference theory, we analyse the theoretical transmission spectra and make the simulation, which is realized by two-dimensional finite-difference time-domain (FDTD) simulation technique. As we expected, the results have a good agreement with the theoretical calculation Small-dimensions, low-loss of the OSs will have an important role in photonic integrated circuits in the future.

A few new methods for fabrication of long period fiber gratings (LPFG) using a CO2 laser fusion splicer are studied and discussed in the article. With the combination of fiber cladding shaping and thermal core expansion, the fabricated LPFG exhibit excellent performance as band pass filters. The insertion loss at 1550 nm band is below 0.5 dB. The entire process for fabricating such LPFGs is fully automated.
