Single Mode Laser Characterisation
Video brought by the Monolithic and Heterogeneous Integration Theme at IPIC, as part of the IPIC 2020 Summer Bursary Programme initiative, discussing single-mode laser structures, simulations and characterization of Fabry Perot/Slotted Fabry Perot/2x2 MMI Laser/1x3.
Contributions made by John McCarthy, a 1st year Ph.D. candidate.
Introduction to Photonic Integration Methods
Video brought by the Monolithic and Heterogeneous Integration Theme at IPIC, as part of the IPIC 2020 Summer Bursary Programme initiative, providing a general overview of the various methods used to integrate optical devices with the silicon photonic platforms to form a highly functioning photonic integrated circuit with the aid of micro transfer printing.
Introduction to Monolithic and Heterogeneous Integration Theme
An introductory video brought by Brian Corbett, the director of Monolithic and Heterogenous Integration Theme at IPIC.
Introduction to Micro Transfer Printing
Video brought by Monolithic and Heterogeneous Integration Theme at IPIC, as part of the IPIC 2020 Summer Bursary Programme initiative. Includes a brief introduction to silicon photonics and the need for its integration with active material, a summary of various heterogeneous integration techniques and advantages of Micro Transfer Printing over other methods, a detailed explanation on the principles of Micro Transfer Printing, the underlying theory, mandatory steps in executing the technique and areas of application.
What is Photonics?
Photonics is the study of light. Photonics research focuses on generating, controlling and detecting photons, the building blocks of light. Photonics is present in our everyday loves from the lighting in our streets and homes to the technology we use to communicate with each other. The Irish Photonic Integration Centre or IPIC, based at Tyndall National Institute in Cork, is a SFI research centre for excellence and focuses on light-based technologies. IPIC’s research areas include medical devices, quantum technology, augmented reality, renewable energy and optical communications, amongst many other research topics.
Optical Coherence Tomography for Biological Imaging
Carlos Reyes is working in the Biophotonics research group of the Irish Photonic Integration Centre, located at the Tyndall National Institute. His research focuses on the set up and optimization of an optical coherence tomography station, which he built and assembled during his PhD project. Carlos is enthusiastic about applying the biomedical imaging to ex-vivo tissue samples or any other biological materials. Apart from that, his work requires him to use a number of mathematical software packages, such as MATLAB, LabVIEW and Python.
Communication Lasers using GaAs materials
GaAs based devices are emerging as a scalable, cheap alternative to the more commonly used InP based devices to achieve wavelength emission in the 1.3-1.55 micron range desired for data and telecommunication applications. In addition, GaAs-based lasers also have superior optical and carrier confinement, allowing for operation at higher temperatures. However, it is difficult to achieve larger than 1.3-micron wavelength emission due to the highly strained layers in GaAs. By employing a metamorphic buffer layer that follows a parabolic design, we demonstrate lasing at 1350 nm in GaAs-based lasers.
