Abstract: An optical wavelength monitor photodiode integrated on a wafer and/or an optical device and coupled to optical components thereof provides wavelength measurement. The optical wavelength monitor includes a photodiode configured to output a signal that is representative of a wavelength of the light. An additional photodiode may be included in the optical wavelength monitor, each photodiode differing from the other in operating characteristics. The monitor may be used in testing the optical device while in wafer form and when the optical device has been cleaved from the wafer at the bar level. Testing/monitoring of the optical device may also be performed during use, for example, to control the wavelength of a laser such as a tunable laser.

Abstract: A locking handle for a refrigerator includes a mounting element rigidly secured to a refrigerator door, a hand grip rigidly secured to the mounting element, and a latch attached to the mounting element. The latch has a catch movable between a locked position and an unlocked position and an actuator operably connected to the catch for moving the catch from the locked position to the unlocked position. The latch provides a positive lock which is actuated to an unlocked position with a manipulation separate from pulling the hand grip but has an actuator located near the hand grip so that it can be manipulated by a hand grasping and pulling the hand grip. In a first embodiment, the catch is integrally molded with the mounting portion and is laterally deflectable away from a retainer mounted beside the door. In a second embodiment the catch is a vertically extending spindle which is downwardly movable away from a retainer mounted above the door.
