Title: John Douglas Lambkin: Innovator in Optical Technology

Introduction

John Douglas Lambkin is a notable inventor based in County Cork, Ireland. He has made significant contributions to the field of optical technology, holding 2 patents that showcase his innovative spirit and technical expertise.

Latest Patents

One of Lambkin's latest patents is an optical fibre connector. This connector is designed to receive and grip an optical fiber in alignment with an optical element. It features pivoting portions that are held in a default inoperative position by the spring action of molded hinges. In this position, two shutter portions meet, forming a barrier that prevents dirt from entering the optical element. As the optical fiber is pushed a small distance into the connector, the pivoting portions pivot slightly about the hinges, allowing teeth to engage with the fiber's outer jacket. This design ensures a secure connection while maintaining cleanliness.

Another significant patent is for a light-emitting diode (LED). This green LED includes a substrate, a GaN heavily n-doped bottom confining layer, an active region, an upper GaN confinement layer, and a semi-transparent ohmic contact layer. The active region contains up to three highly compressively strained quantum wells, with widths less than 3 nm. This arrangement results in a short free carrier life-time, which enhances the modulation bandwidth of the LED.
