Lead silicate microstructured optical fibres for electro-optical applications

Abstract

We report progress towards the realization of optical modulators based on electro-optic effects in soft glass fibres. A hybrid fabrication procedure was developed for producing microstructured lead silicate glass fibres with internal electrodes. Electro-optical characterization confirms experimentally that the enhanced nonlinear properties and superior isolation between the optical field and the electrodes make these fibres an ideal candidate platform for efficient electro-optical devices.

Nanomechanical Optical Fiber with Embedded Electrodes Actuated by Joule Heating

“…Many of these efforts were focused on control of dispersion, enhancement of the nonlinearity, reduction of the fiber transmission loss, or increase of sensitivity to environmental conditions in single-material MOFs [ 5 ]. Multi-material MOFs have also been developed for added functionality, e.g., hollow-core fibers filled with liquids [ 6 ] or gases [ 7 ] for sensing, with gases for high-power pulse compression [ 8 , 9 ] and nonlinear effects [ 10 , 11 ], with semiconductors for electronic functionality [ 12 ], and with integrated electrodes [ 13 , 14 ] and liquid crystals [ 15 ] for optical switching.…”

Supercontinuum generation in dispersion-varying microstructured optical fibers

“…However their initial seed pulse was at 3.5 μm which is not at the telecommunications wavelength; also the length of the fiber is longer than we used here. In [13], SC was produced in dispersion tailored all-solid soft glass photonic crystal fibers pumped at 1550 nm. However, the spectrum broadening was mainly caused by self-phase modulation and four wave mixing rather than soliton dynamics.…”

“…Microstructure fabrication technique has been widely applied to non-silica glasses [10][11][12][13][14][15][16][17][18]. Here we choose SF57 as the material for the MOF.…”

“…It has a solid core surrounded by an array of air holes rendering the cladding region with an average refractive index lower than that in the core. Various types of glass such as lead-silicate [11][12][13], fluoride [14] and chalcogenide glass [15,16] have been introduced as core materials in MOFs. The guidance properties of MOFs make it possible to engineer the dispersion characteristic, which is critical to achieving broadband SC.…”

Tellurite-based core-clad dual-electrodes composite fibers

“…In addition, low-T g glass systems exhibit moderate processing temperatures, allowing for a larger panel of potential metals to be co-drawn with. Monro et al identified tellurite glasses as being especially suitable for electro-optical fiber devices, owing to their large nonlinear coefficients and drawing ability [4,5]. Here post-drawing liquid metal injection was employed for providing optical fibers with internal electrodes.…”
