Title: Innovations of Tibor F Devenyi
Introduction
Tibor F Devenyi is a notable inventor based in Nepean, Canada. He has made significant contributions to the field of laser technology, holding a total of five patents. His work focuses on enhancing the performance and reliability of laser diodes, which are crucial components in various optical applications.
Latest Patents
One of his latest patents is the "Laser-fiber positioner." This invention aims to position a light output device, such as a laser diode, relative to a light device like a waveguide to achieve maximum light coupling. The waveguide end facing the laser is vibrated mechanically to modulate the coupled light. Light is detected from a remote end of the fiber, generating a corresponding electrical signal. The positional information contained in the oscillatory component of the signal is decoded and applied to a positioning device, which continuously seeks the maximum coupling position. This technique is particularly useful in positioning a waveguide in a laser package before and during anchoring.
Another significant patent is the "Method for screening laser diodes." This method involves screening double heterostructure laser diodes before mounting and packaging. At normal operating temperatures, a range of pulsed current is passed through the laser diode while monitoring the lasing threshold current and slope efficiency. The diode undergoes a burn-in process at high junction temperatures for an extended period. Afterward, the lasing threshold current and slope efficiency are monitored again. If either parameter changes beyond a predetermined amount, the laser diode is rejected. Otherwise, it is considered likely to have a longer lifetime under normal operating conditions, warranting further testing before installation into a laser package.
