Interconnected Porous Hydrogels with Tunable Anisotropy Through Aqueous Emulsion Bioprinting

open access: yesAdvanced Functional Materials, EarlyView.
A 3D bioprintable microporous bioink is developed using an aqueous two‐phase system (ATPS) composed of extracellular matrix (ECM) mimetic biopolymers. The ATPS bioink enables the fabrication of interconnected porous architectures with up to 70% porosity, supporting long‐term cell viability and 3D cell alignment, enabling a simultaneous generation of ...

Serpentine Integrated Grating Spectrometer

OSA Imaging and Applied Optics Congress 2021 (3D, COSI, DH, ISA, pcAOP), 2021
The serpentine integrated grating spectrometer uses a meandering delay line and outcoupling grating rows to implement a crossed-dispersion wide-bandwidth integrated spectrometer with resolving power of 105 and 104 spectral bins in a few cm3 volume.

Recent developments in integrated spectrometers

Proceedings of 2004 6th International Conference on Transparent Optical Networks (IEEE Cat. No.04EX804), 2004
In the 1990s, the Institute for Microstructural Sciences has maintained a research project on wavelength division multiplexing (WDM) based on integrated echelle gratings spectrometers. Major obstacles to the application of these spectrometers to telecommunications, such as channel wavelength accuracy, insertion loss, birefringence, polarisation ...

Miniature Integrated Spectrometer Array

2019 24th Microoptics Conference (MOC), 2019
We describe the design and set-up an array of micro-spectrometers for parallel sensing. The approach utilizes a prism – grating combination to obtain a linear light path and to achieve a high packing density. This yields 2’000 micro spectrometers of 6 mm length only when working with a 4/3” CCD image sensor.
