Monolithic opto-isolators and arrays of monolithic opto-isolators are disclosed. The monolithic opto-isolators are manufactured in a single semiconductor wafer where they may be tested at the wafer level before each opto-isolator is singulated from the wafer. The monolithic opto-isolators include a VCSEL monolithically produced adjacent to a photodiode where an axis of optical signal transmission of the VCSEL is substantially parallel to an axis of optical signal reception by the photodiode.

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.

A method and system is disclosed for locking and releasing a module utilized in a transceiver system that includes a plurality of modules in close proximity with one another. The module is generally configured to include a handle with an associated cam formed in a first section of the module. The handle is moveable in a direction to allow the cam to move an associated ejector button integrated with the module in order to release the module from the transceiver system, thereby permitting the module to be efficiently removed from the transceiver system. The module may thus be removed from the transceiver system utilizing the handle. The module may be locked into the transceiver system when the handle is placed in an upward position.

Reducing transmission of electromagnetic waves through a barrel portion of an optical module. A barrel for optically coupling an optical device to an optical fiber within a fiber optic cable can include a plastic portion and a metallic shielding portion for reducing transmission through the barrel. An optical device can be coupled to the plastic portion. The metallic shielding portion can be coupled to the plastic portion and surround at least a portion of the plastic portion. The metallic shielding portion can be shaped and configured so as to reduce transmission of electromagnetic radiation through the barrel.
