Abstract
A power monitoring device includes: a silicon support layer being attached to a PCB board; a glass layer disposed above the silicon support layer; at least one sensing element disposed on the glass layer; and at least one metal pad disposed on the glass layer. The sensing element is suspended over a laser element that is attached to the PCB board and configured for sensing light directed thereto that is emitted by the laser element. A cavity is defined in the silicon support layer and configured for accommodating the laser element. A transmitter that includes the power monitoring device is also provided.
