We propose a novel and simple method to fabricate aperiodic subwavelength nanostructures by Grayscale Interference Lithography (GIL) with the conventional Lloyd's mirror interferometer and a movable aperture plate.
The two oft-used techniques of photonic crystal fabrication namely holographic lithography and direct laser writing have been combined to generate hexagonal photonic crystal lattice with a chiral basis having an extrinsic defect etched into it. The presented results show the realization of possible building blocks which could be tailored as polarization specific optical devices for photonic integrated...
As a method of combining holography and photoinduced polymerization techniques, holographic lithography (HL) has been extensively applied in fabricating mesoscale structures such as photonic crystals recently because of the advantages of flexibility, convenience and high efficiency over some other conventional techniques. In this contribution, we demonstrate the fabrication of visible photonic band...
Penrose-type photonic quasi-periodic crystals are fabricated through 5 or 6 beam holographic lithography using a lab-made phase mask. The quasi-crystal structure is confirmed through diffraction patterns showing ten-fold symmetry.
This study demonstrates the use of electronically coupled patterned quantum dots (QDs) fabricated using a wet-etching technique as the gain medium of a photonic device. This technique provides the unique ability to control both the spatial and spectral properties of QDs, while maintaining the high optical quality of the material necessary for photonics applications.
This paper describes femtosecond laser lithography of 3-D photonic crystal templates in commercial photoresist SU-8 and replication of these templates with silicon. Using this approach, silicon-based photonic crystals having 3-D square spiral architecture and exhibiting photonic stop gaps near the 2.5- mum wavelength were fabricated. Possibilities to use a multiple-beam interference technique for...
