An interface or communications system for a neural probe, the interface or communications system comprising at least one probe interface, an optical communications interface and a processing system. The at least one probe interface is configured to interface with at least one neural probe so as to receive data collected by the probe. The processing system is configured to process the data from the at least one probe interface and provide the processed data to the optical communications interface. The optical communications interface is configured to communicate the processed data to a remote device, e.g. using optical wireless communications. The optical communications interface has the large bandwidth available that will allow the scaling up of recording sites from the neural probe without resulting in undue size, weight and/or power consumption.

Neural probe interface system and method

There is herein described light emitting medical devices and a method of manufacturing said medical devices. More particularly, there is described integrated light emitting medical devices (e.g. neural devices) capable of being used in optogenetics and a method of manufacturing said medical devices.

Integrated medical device

An array of light emitting devices, each device comprising a sloped wall mesa () of luminescent semiconductor material. Extending over the sloped wall mesas () is a metal contact (). The array can be arranged as a parallel addressable system so that all devices () can be stimulated to emit light simultaneously. Alternatively, the array can be arranged as a matrix addressable array, in which case individual devices can be selectively stimulated.

Micro-leds

A method of growing semiconductor materials in the Indium, Aluminium, Gallium Nitride (InAlGaN) material system and to devices made therefrom, in particular optical devices in the ultraviolet to green region of the visible spectrum. Certain optical devices, for example Vertical Cavity Surface Emitting Lasers (VCSELs) require great precision in the thickness of certain semiconductor layers. One aspect of the present invention provides a gallium-rich group III nitride layer () and an adjacent layer of AlInGaN layer (). The AlInGaN layer () acts as a fabrication facilitation layer and is selected to provide a good lattice match and high refractive index contrast with the gallium-rich group III nitride layer (). The high refractive index contrast permits in-situ optical monitoring. The extra layer () can be used as an etch marker or etch stop layer in subsequent processing and may be used in a lift-off process.

Method of fabricating semiconductor devices with a multi-role facilitation layer

A solid-state, surface-emitting, optical device such as a light emitting diode (LED) or vertical cavity surface emitting laser (VCSEL) has a body of optical gain medium overlying a high reflectivity distributed BRAGG reflector (DBR) mirror which is carried on part of an underlayer. The gain layer is part of an epitaxial layered structure extending from the underlayer over the mirror.

Optical devices

The light emitted by diodes of the Gallium Nitride type which comprises two distinguishable emissions is controlled by a single optical element (,) in the form of a lens having a central part and an annular part with different optical powers. The total output light of the diode may be collimated or brought to a common focus. The single optical element is preferably injection moulded and the annular part takes the form of a diffraction lens. The first part (,) is preferably a refractive lens which has a different optical power to the second part (,)which is preferably a diffractive lens. The optical power of the refractive lens (,) (the first optical power) and the optical power of the diffractive lens (,) (the second optical power) are selected to match the light source that the lens (,) is to be used with.
