Organic-based distributed feedback lasers by direct electron-beam lithography on conjugated polymers

Two-dimensional Bragg grating lasers defined by electron-beam lithography

Two-dimensional Bragg grating 2DBG lasers with two quarter-wave slip line defects have been designed and fabricated by electron-beam lithography and reactive ion etching. Unlike conventional two-dimensional photonic crystal defect lasers, which use a large refractive index perturbation to confine light in a plane, the 2DBG structures described here selectively control the longitudinal and trans...

Study on polymers with implementation in electron beam lithography

In this chapter, we present a study on three polymer resists that are important for electron beam lithography (EBL) and we demonstrate their successful application for nano-structuring and EBL process optimization. The experiments performed showed that the resists behavior, including their sensitivity and contrast, is influenced by the energy of the electrons, by the nature of the resists and u...

Efficient organic distributed feedback lasers with active films imprinted by thermal nanoimprint lithography

Organic solid-state lasers (OSLs) have been a subject of intense research for many years [1] mainly due to the various advantages of organic materials, such as easy processability, chemical versatility, wavelength tunability and low cost. Among the various types of resonators used in the field of OSLs, distributed feedback (DFB) structures are probably the most extensively studied. As compared ...

Electrochemical Sensors Based on Organic Conjugated Polymers

Organic conjugated polymers (conducting polymers) have emerged as potentialcandidates for electrochemical sensors. Due to their straightforward preparation methods,unique properties, and stability in air, conducting polymers have been applied to energystorage, electrochemical devices, memory devices, chemical sensors, and electrocatalysts.Conducting polymers are also known to be compatible with...
