Athermal AWGs in SOI by overlaying a Polymer Cladding on Narrowed Arrayed Waveguides
Integrated Optics Components Integrated Optics Devices
2015/5/22
Athermal AWGs in SOI are experimentally demonstrated for the first time to our knowledge. By using narrowed arrayed waveguides and overlaying of polymer, we obtain a wavelength temperature dependence ...
Experimental verification of higher-order mode suppression in a bent large-mode-area multi-cladding fiber
Fiber design and fabrication iber properties
2015/6/9
A novel technique to suppress the higher-order mode in a bent large-mode-area triple-cladding fiber is experimentally presented. 3-dB suppression of LP 02 mode is observed on a fabricated triple-cladd...
Simple suppression technique for higher-order mode amplification in bent large mode area triple-cladding fibers

2015/6/4
A novel technique to suppress the higher-order mode in bent LMA triple-cladding fibers is proposed. It is shown that the higher-order mode can be coupled to a cladding mode with only an adjustment of ...
First Demonstration of Photonic Bandgap Guidance in Hollow-core Photonic Bandgap Fibres with Square Lattice Cladding
Photonic Bandgap Guidance Hollow-core Photonic Bandgap Fibres Square Lattice Cladding
2015/7/20
Square lattice with much higher node-to-strut ratio is promising for significantly extending bandgaps in hollow-core fibres. First such fibres are achieved here. Minimum loss of 67dB/km is demonstrate...
Bend-Insensitive and Effectively Single-Moded All-Solid Photonic Bandgap Fibers with Heterostructured Cladding
Bend-Insensitive Effectively Single-Moded All-Solid Photonic Bandgap Fibers Heterostructured Cladding
2015/7/14
We propose a novel concept of cladding structure in all-solid photonic bandgap fibers. It promises low bending and confinement losses with single-mode operation. The mechanism is based on the new conc...
Observation and analysis of cladding modes in photonic crystal fiber
Observation analysis cladding modes photonic crystal fiber
2015/7/14
We report the observation of cladding modes that are the lowest-order modes having the major optical power in the air-hole region of a photonic crystal fiber. The field profiles agree well with numeri...
