A machining tool, especially a milling tool, includes a shaft-like holder defining a longitudinal axis (13). A seat (9) is provided in the front face of the holder for a cutting plate that can be inserted into the holder. The cutting plate has a coupling part for mounting in the seat (9) of the holder.

A photodetector for detecting infrared radiation (IR) using a slab waveguide is described. The slab waveguide photodetector operates by resonating transverse magnetic or electric modes within the slab from the incident IR. An IR absorbing layer is located within the slab waveguide photodetector where the magnitude of the electric field vector is greatest. This permits the use of a thinner IR absorbing layer without sacrificing photoresponse. Multi-color slab waveguide photodetectors are permitted because multiple transverse magnetic or electric modes resonate within the slab waveguide. A reflective or transmissive grating is used to launch the IR into the IR absorbing layer through a cladding or antireflection layer.
