An opto-isolator is disclosed that include a vertical cavity surface emitting laser (VCSEL), a photodetector and a package enclosing the VCSEL and the photodetector. The photodetector is optically coupled to the VCSEL and configured to receive an output optical signal generated by the VCSEL.

Opto-isolator including a vertical cavity surface emitting laser

The present invention relates to opto-isolators. Opto-isolators are disclosed that include a transmitter package and a vertical VCSEL disposed within the transmitter package. The opto-isolators further include a receiver package and a photodetector disposed within the receiver package. The photodetector is optically coupled to the VCSEL and configured to receive an output optical signal generated by the VCSEL. The opto-isolators further include an alignment package configured to receive the transmitter package and the receiver package. In another embodiment, opto-isolators include a VCSEL and a photodetector optically coupled to the VCSEL and configured to receive an output optical signal generated by the VCSEL. The opto-isolators further include a package enclosing both the VCSEL and the photodetector.

The present invention relates to controlling parameters of an optical output of an optical transmitter. An optical package can be selected based on a level of attenuation of a parameter of a transmitter output by the optical package. The laser and the optical package can be assembled and a parameter of the transmitter output can be measured. An optical barrel can be selected based on the measurement, wherein the optical barrel is selected based on an attenuation level to satisfy a range of a desired parameter value. The optical package and the optical barrel can be assembled. A system for assembling the optical device is also described.

Attenuated barrel selection algorithms

Optical sensor methods and systems for detecting the edge of an object are disclosed. An optical sensor having dual equal area active regions can be provided, and a uniform light source located opposite the optical sensor, such that an occlusion of light from the uniform light source provides location determination data of an object via the optical sensor regardless of the direction of motion of the occlusion relative to the dual equal area active regions thereof.

Opto-electronic transmissive edge location sensor

A versatile system and method for VCSEL (vertical cavity surface emitting laser) bar code and data scanning is disclosed, including a housing ( ) having a scanning surface ( ), a detector element ( ) disposed within the housing in close proximity and normal to the scanning surface, a VCSEL component ( ) disposed within the housing in close proximity to the detector element and scanning surface, and an aperture ( ) formed within the housing between the scanning surface and the detector element.
