| Abstract: | In this paper,a new all optical tunable phase shifter is introduced.The principle is that the clearance in gas gap is tunable by precision mechanism.It can realize the phase adjustment in ps stage of optical signal at high speed directly in optical domain.The large adjustable value is 600ps,insertion loss is 7dB and adjustable precision is 0.03ps.The measurement method of optical phase in precisely is also given.It is accomplished firstly in P.R.China.It is very important for optical packet switching,optical time division multiple and optical signal processing,etc. |
