When it is detected, based on the gaze directions, that the user is looking through a predefined portion of the active optical element, a drive signal is generated to drive said means to control the active material to produce a predefined optical power. When it is detected that the user's gaze is moving towards a periphery of the predefined portion, at least one other drive signal is generated to drive said means to control the active material to produce at least one intermediate optical power lying in a range between a zero optical power and the predefined optical power.Type: GrantFiled: February 11, 2022Date of Patent: March 12, 2024Assignee: Pixieray OyInventors: Klaus Melakari, Rebecca Qing Melakari

Patent number: 11927839Abstract: An electro-absorption modulator (EAM) is configured to include an on-chip AC ground plane that is used to terminate the high frequency RF input signal within the chip itself. This on-chip ground termination of the modulation input signal improves the frequency response of the EAM, which is an important feature when the EAM needs to support data rates in excess of 50 Gbd. By virtue of using an on-chip ground for the very high frequency signal content, it is possible to use less expensive off-chip components to address the lower frequency range of the data signal (i.e., for frequencies less than about 1 GHz).Type: GrantFiled: September 14, 2020Date of Patent: March 12, 2024Assignee: II-VI Delaware, Inc.Inventors: Andrei Kaikkonen, David Adams, Robert Lewen, Nicolae Chitica
