We report on stable dual-wavelength operation in passive and hybrid mode-locking of a 10GHz two-section InAs/InP(100) quantum dot laser diode operating at 1.5μm. The range of stable passive mode-locking, the locking range of hybrid mode-locking and detailed measurements of the phase modulation in the output pulses will be presented.

Hybrid systems can switch between many operating modes where each mode is governed by its own characteristic dynamical laws. Mode transitions are triggered by variables crossing specific thresholds (state events), by the lapse of certain time periods (time events), or by external inputs (input events). A simple example of a hybrid system would be a car. The dynamics of the car switch when a gea...

the cytoplasmic male sterile (cms) lines that are used in production of hybrid seeds in three-line system often get contaminated with their maintainer lines. using such impure cms lines in rice hybrid seed production lead to un-uniformity and yield loss in hybrid rice. laborious and time consuming phenotypic evaluations are used for elimination of off-type plants in cms multiplication farms. th...

Today competitive environment has enforced practitioners and researchers to pay great attention to issues enhancing both production and marketing competitiveness. To do so, it has been obligatory for the firms to consider production side activities while customer requirements are on the other side of competition. In this regard, hybrid make-to-stock (MTS)/make-to-order (MTO) production systems ...

in order to evaluate the effect of different planting patterns and different varieties of corn on quantity management in 2015 as a split-plot in a randomized complete block with 3 replications. the test pattern as the main factor in two levels in the atmosphere and the stack corn hybrids in four sub-levels maxima, asv3, magi 704 and 400 were hybrids. the effect of planting pattern, the maximum ...

Mode locked pulse generation has been reported using both active and passive mode locking schemes. Active mode locking technique has been proven to be an effective way to generate high-repetition-rate pulses by incorporating a modulator inside the laser cavity. Compared to actively mode locked lasers, passively mode locked lasers can generate pulse train at ultrashort pulse width but with relat...

This paper describes the development and experimental validation of a multi-layer hybrid controller for optimizing energy management in a solar air conditioning plant. The hybrid nature of the process is due to its multi-mode structure: the refrigeration circuit can be fed by flat solar collectors, a storage system, by an auxiliary gas heater, or by a combination of them. The selection of the o...

Hybrid systems consist of continuous and discrete dynamics. These systems can be described with a set of modes, where in each mode the system is governed by a continuous dynamics, and different modes correspond to different continuous models. For hybrid systems, model-based fault detection and isolation (FDI) is a challenging task, since system’s prevailing dynamical model and the system's curr...

This paper evaluates the performance of a grid connected hybrid system. The hybrid system consists of a Photovoltaic (PV) array and a Proton exchange membrane fuel cell (PEMFC). Two operation modes, the unit-power control (UPC) mode and the feeder-flow control (FFC) mode, can be applied to the hybrid system. The objective of the paper is to coordinate the two control modes and determine the ref...
