Abstract :
Time resolved polarisation characteristics of 1.3 mu m GaInAsP/InP-RW lasers are presented, showing the switching behaviour between the TE and TM mode as well as polarisation bistability. A switching time of about 50 ps is observed for the transition between TE and TM polarisation under 900 MHz current modulation. This is the shortest switching time measured so far.
