Photonic crystal microchip laser [PDF]
SPIE Proceedings, 2016 AbstractThe microchip lasers, being very compact and efficient sources of coherent light, suffer from one serious drawback: low spatial quality of the beam strongly reducing the brightness of emitted radiation. Attempts to improve the beam quality, such as pump-beam guiding, external feedback, either strongly reduce the emission power, or drastically ...

Loss analysis of air-core photonic crystal fibers [PDF]
, 2003 By using a multipole moment approach, we analyze the loss of an air-core photonic crystal fiber and demonstrate that it is possible reduce the transmission loss that is due to photon radiation leakage through the photonic crystal cladding to a level ...

Photonic crystal for graphene plasmons
Nature Communications, 2019 Photonic crystals are commonly implemented in media with periodically varying optical properties. Photonic crystals enable exquisite control of light propagation in integrated optical circuits, and also emulate advanced physical concepts. However, common

Room temperature continuous wave operation of single-mode, edge-emitting photonic crystal Bragg lasers [PDF]
, 2008 We report the first room temperature CW operation of two dimensional single-mode edge-emitting photonic crystal Bragg lasers. Single-mode lasing with single-lobed, diffraction limited far-fields is obtained for 100μm wide and 550μm long on-chip devices ...

Photonic crystal fibre characterisation with the method of lines
Journal of Telecommunications and Information Technology, 2004 Photonic crystal fibres are longitudinally uniform fibres in which in lateral directions periodic refractive index changes occur. Two basically different light guiding mechanisms occur in crystal fibres: index guiding and bandgap guiding.

Magnetic photonic crystals [PDF]
Journal of Physics D: Applied Physics, 2003 In this paper we outline a new direction in the area of photonic crystals (PCs), or photonic band gap materials, i.e. one-, two-, or three-dimensional superstructures with periods that are comparable with the wavelengths of electromagnetic radiation.
