“…DFB-EEL structures that don't require epitaxial regrowth have also been realized but their fabrication was based on expensive electron-beam lithography (e.g. Miller et al 1991;Martin et al 1995;Schreiner et al 2001;Müller et al 2002).…”

The paper presents some model improvements for the optical simulation of laterally-corrugated ridge-waveguide distributed feedback lasers. Simulation results are discussed and design principles for achieving single-longitudinal-mode operation are outlined. The effects of the laterally-corrugated ridge geometry both on the coupling coefficient and on the Bragg wavelength of different transverse modes are presented. The improved modeling has been used to design 980 nm distributed feedback lasers with laterally-corrugated ridge-waveguide third-order gratings. The lasers fabricated using nanoimprint lithography exhibited single-mode operation with 50 dB side-mode suppression ratio.

“…The problematic overgrowth can be avoided by using surface gratings. Laterally-coupled DFB (LC-DFB) structures, either index-coupled (based, for example, on lateral corrugation of the ridge-waveguide (RWG)) or complex-coupled (based, for example, on metal gratings placed perpendicular on the sides of the RWG), have been realized with electron-beam lithography (Miller et al 1991;Martin et al 1995;Schreiner et al 2001;Müller et al 2002;Jang et al 2008).…”

Laterally-corrugated ridge-waveguide distributed feedback lasers at 980 nm

et al. 2009

The paper presents a simulation-based analysis of laterally-corrugated ridgewaveguide distributed feedback semiconductor lasers emitting at 980 nm. The simulations were performed using software developed in-house and the PICS3D software package from Crosslight Software Inc. The effects of the corrugation geometry, phase-shift section, and mirror reflectivities on single longitudinal mode operation are discussed. The lasers, designed along the guidelines derived from the simulation results, were fabricated by using molecular beam epitaxy for wafer growth and low-cost nano-imprint lithography. They exhibited stable single-mode operation with up to 50 dB side-mode suppression ratio.

“…However, fabricating these lasers requires both high-resolution processing and complex regrowth steps. Laterally coupled DFB lasers [1], [2] and surface-grating distributed Bragg reflector (DBR) lasers [3] which use just a single growth step have thus attracted great interest. However, these devices generally need electron-beam lithography for patterning which is quite expensive compared with the standard photolithography.…”

Abstract-A single-mode laser structure suitable for photonic integration is presented. The laser can be fabricated by standard photolithography without any regrowth steps. Through optimization, a threshold current as low as 13 mA and a sidemode suppression ratio (SMSR) up to 47 dB have been predicted for a 400-m -long laser. A high yield up to 90% is also predicted with the requirement that the SMSR is higher than 40 dB at an injection current of 100 mA.
