A performance, analytics and auditing system is configured to operate with a complex web application including a portal application and its sub systems non-intrusively. The tilted wave laser includes a narrow active waveguide coupled to a broad passive waveguide, and light generated in the active waveguide leaks to the broad waveguide and propagates in it in the form of a tilted optical wave. One of the housing parts has at least one filling opening, which opens into the cavity, for filling with a curable encapsulation compound, and with the cured encapsulation compound surrounding the cable ends in the area of the connecting terminal, and being joined to the housing parts. The strain is in turn transmitted to the microbeam 11, thereby affecting its resonant frequency.
