Glass Fibre Optics General Set-up:

This set-up has been made with a multimode fibre. Because of didactic reasons a bare fibre without extra protective coating has been selected. The cut and cleaved fibre is put into the groove of holder (12) and carefully fixed with the two magnets. The laser diode in its housing (9) is mounted on a four axes fine adjustment holder. A Peltier cooler and a thermistor for measuring the laser diode temperature are built into the housing. The laser diode emits a maximum power of 50 mW as laser of class 3B. A microscope objective (10) collimates the laser diode radiation. The module (11) consists of a fine adjustment holder with four axes and an objective of smaller focal length to focus the collimated laser diode radiation in such a way that an effective coupling to the fibre is ensured. 1000 m multimode fibre (5) are coiled up on a drum. The second fibre holder (13) is mounted on a hinged joined angle connector. The module (14) consists of the detector with a PIN photodiode and is mounted on top of the pivot arm. By turning the arm the angle resolved intensity distribution either of the laser diode or the fibre output can be measured. The module is connected to the signal conditioner box (7) where a BNC socket is provided to connect the output either to an oscilloscope or digital multimeter
