Broadband EO-Comb Generation Based on Two-Stage Nonlinear System

Broadband degenerate OPO for mid-infrared frequency comb generation.

We present a new technique suitable for generating broadband phase- and frequency-locked frequency combs in the mid-infrared. Our source is based on a degenerate optical parametric oscillator (OPO) which rigorously both down-converts and augments the spectrum of a pump frequency comb provided by a commercial mode-locked near-IR laser. Low intracavity dispersion, combined with extensive cross-mi...

Rule Generation Based on Novel Two-stage Model

Purpose – The purpose of this paper is to develop a novel two-stage model for promoting the effect of rule generation based on rough set. In order to improve traditional rough set method, the novel two-stage model adopts new kernel intuitionistic fuzzy clustering (KIFCM) to promote performance of rough set theory. Moreover, the e-learning customer data set in Taiwan is also examined for demonst...

Next-generation Broadband Wireless System

INTRODUCTION AS optical fiber networks have become available to end users, the type of content being accessed on the Internet is changing away from text and imageoriented information towards high-volume data such as sound and video. At the same time, there is a growing trend towards the combined use of personal computers and mobile terminals (e.g. mobile phones) because using a mobile terminal ...

Two-stage linear-nonlinear shaping of an optical frequency comb as rogue nonlinear-Schrödinger-equation-solution generator

Two-stage column generation

We introduce a new concept in column generation for handling complex large scale optimization problems, called two-stage column generation, where columns for the compact and extensive formulation are simultaneously generated. The new framework is specifically conceived for tackling complex problems that cannot be efficiently solved by standard column generation and exploits the relationship bet...
