In this paper, we study the efficiency of inter-domain state advertising in multi-domain networks, in which the intra-domain topology is substituted with a full-mesh topology of abstract links interconnecting the border nodes of the domain. The advertising trigger rate of individual abstract link is taken as the metric of efficiency. We present an analytical model that reveals the contributions of different physical links to the advertising trigger rate of individual abstract links. According to the model, we propose a state based advertising mechanism, called partial link based advertising (PLA) which can discern and advertise the state variation of individual abstract link by monitoring only a portion of physical links. We formulate the problem of how to optimally selecting physical links to monitor, and provide a heuristic algorithm for link selection. Results show that the PLA performs more efficiently than existing mechanisms in terms of advertising trigger rate and blocking probability.

The paper presents a novel energy efficient routing scheme for photonic network on chip (PNoC) based on the microresonator which takes the insertion loss and the path-setup latency into consideration in order to design a high performance per watt multi-processors. The path-setup latency is a major contributor to the whole system's latency that has something to do with queuing. And insertion loss which has impact on power consumption is closely related to the number of micro-resonators in on state. To solve the multi-objective optimization problem, we design a straight line first heuristic routing scheme. The goal of this routing scheme is to reduce the path-setup latency and insertion loss. Simulation results show that this scheme can low the latency with lower the insertion loss as little as possible.

We demonstrate the long linear-cavity with ultra-low repetition rate Ytterbium-doped fiber laser mode-locked by a SESAM. Output pulses were highly-chirped, with energies high to 75.2 nJ and minimum repetition rate was 191 kHz.
A simple, convenient and accurate technique for measurement of time delay in fiber by using a free-running linear-cavity laser is demonstrated. The uncertainty of time delay was in the order of 10 -7 ~ 10 -6 .
