We have developed a novel dispersion-reduction technique using subcarrier multiplexing (SCM) which permits the transmission of multiple 2.5 Gbit/s data channels over hundreds of kilometers of conventional fiber-optic cable with negligible dispersion. Using a lithium niobate external modulator having a modulation bandwidth of 20 GHz, we are able to multiplex several highspeed data channels at a ...

Introduction: The operation of a laser in a stable single fundamental mode is important for a variety of applications, such as short and midrange optical networks (high quality local area networks and storage area networks). For these purposes, vertical cavity surface-emitting lasers (VCSELs) show more promise in many cases over distributed feedback (DFB) lasers for a variety of reasons: easy a...

Title of Dissertation: BENZOCYCLOBUTENE MICRORING RESONATORS Wei-Yen Chen, Doctor of Philosophy, 2007 Dissertation Directed By: Professor Ping-Tong Ho Department of Electrical and Computer Engineering Wavelength division multiplexing (WDM) at optical carrier frequencies offers more capacity and flexibility of fiber networks and upgrades conventional point-topoint fiber-optic transmission links ...

for a fiber optical surface plasmon resonance (spr) sensor a short part of its cladding should be removed to coat a thin layer of a metal. usually this is problematic when an optical fiber with small core diameter is used. in this paper, a new method using µliter droplet of the hf acid for short fiber optical taper fabrication is reported. using this method in a multi-mode optical fiber with th...

This paper presents a mathematical model of the sensitive element refractometric fiber-optic sensor principle operation which is based on phenomenon surface plasmon resonance. The sensing design sequential connection multimode fiber (MMF), single-mode (SMF), and forming an MMF-SMF-MMF structure. SMF site coated with thin film gold. To element, approach used in calculating classical Kretschmann ...

We demonstrate wavelength switching in a novel multicavity distributed Bragg reflector semiconductor laser diode. This new device, which uses an integrated saturable absorber and singlemode fiber Bragg gratings, digitally switches wavelength as a function of drive current between all possible binary combinations.

Pada menggu...

An investigation of macrobending loss characteristics of a standard singlemode fiber (SMF28) for small bend radii is presented theoretically and experimentally, which includes the bend loss of the SMF28 with coating layers and the bare SMF28 after stripping the coating layers and chemical etching of partial cladding. The significant influence of reflection occurring at the interface between the...
