Abstract: The present invention provides a self-ejectable port fixing device for contact connecting with a port having a port chip. The port fixing device comprises a casing having an opening through which the port chip is allowed to insert and to contact with a receptacle chip provided in the casing. The port fixing device further comprises an elastic unit and a locking unit. The elastic unit is compressed directly or indirectly by the port so as to accumulate elastic potential energy while the port chip is getting closer to the receptacle chip. When the port chip is in contact with the receptacle chip, the locking unit locks the port chip at this contacting position. When the locking unit is unlocked, the elastic unit releases the elastic potential energy to push the port chip to be detached from the receptacle chip.

Abstract: Apparatus and methods for measuring reflectance of optical laser components are disclosed. In one embodiment, when the reflectance of the test optical laser component is higher than 98%, a cavity ring-down (CRD) technique based configuration is employed to measure the reflectance of the test optical laser component. On the other hand, when the reflectance of the test optical laser component is lower than 98% or there is no measurable CRD signal, by removing the output cavity mirror in the CRD apparatus, a photometric configuration is formed to measure the reflectance. The switching between the two techniques can be achieved by removing or inserting the output cavity mirror of the ring-down cavity in the CRD apparatus.
