A high-efficiency bandwidth product germanium photodetector includes a silicon substrate having an opening-down three-sided groove formed by etching; a metallic reflective mirror layer formed by plating along an internal periphery of the opening-down three-sided groove of the silicon substrate; a light absorbent layer between the metallic reflective mirror layer and a dielectric reflective mirror layer. The light absorbent layer can be p-i-n type or other types. By the use of the critical coupling of resonant cavity, all the incident lights can be completely obstructed in the cavity between the metallic reflective mirror layer and the dielectric reflective mirror layer to reach a critical coupling which means 100% absorption efficiency can be achieved without light leakage. Thus on the basis of the critical coupling, the trade-off between bandwidth and efficiency can be broken through to reach high responsivity and high bandwidth up to 50 GHz by decreasing the germanium layer thickness without sacrificing the light-switch-to-electro absorption efficiency.

The present invention relates to a locking device of an oven grill. When the oven grill is being inserted into the notch of an oven, the inverted V-shaped latch on the locking sheet leans against a bending portion of the V-shaped notch of the oven due to the pulling force exerted by the spring mechanism so as to prevent the oven grill from sliding outwards to lock the oven grill. When the oven grill is to be taken out, put one hand at the front end of the oven and use fingers to lift up the S-shaped tie bar. Then, the rear end of the S-shaped tie bar moves down so as to press down the arc press plate as well as the inverted V-shaped latch such that the locking sheet gets rid of the V-shaped notch under the pulling force exerted by the spring mechanism and, in turn, the locking at two sides are removed simultaneously, thus the oven grill can be taken out evenly and smoothly using one hand.
