Fibre Laser Research at Aston Institute of Photonic Technologies

Aston  Institute  of  Photonic  Technologies  (AIPT)  has  a  well  established  track  record  in  many  optical  fibre  related  research  areas.  The  recent  development  in  fibre lasers by exploiting the nonlinear effects, polarised fibre gratings and nanomaterials has put AIPT in a leading position in novel optical fibre laser technology and applications.

Ultralong Fibre Laser

aipt_fibrelaser2
AIPT  was  the  world  first  proposed  and 

developed  ultralong  fibre  lasers  with  cavity 
length  up  to  tens  and  hundreds  km  by 
uniquely  exploiting  Raman  amplification 
effects in the fibre.  Recently, a world record 
of  270  km  has  been  reported  by AIPT.  The 
demonstration  of  the  ultralong  fibre  lasers 
leads to a radical new outlook on information 
transmission and secure communications.


Tunable Random Distributed Feedback Fibre Laser

Principle of the random distributed feedback fibre laser
The  concept of random lasers has attracted a great
deal  of  attention  in  recent  years,  however,  the
properties of their output radiation are rather special
and  usually  characterized  by  complex  features  in
the  spatial,  spectral  and  time  domain.  At  AIPT,  a
new  type  of  the  random  fibre  laser  that  is  tunable
over  a  broad  wavelength  range  with  uniquely  flat
output  power  and  high  efficiency  has  been
developed,  which  outperforms  traditional  lasers  of
the same category.  AIPT proposed and demonstrated the random fibre lasers have opened
up a new field in laser physics research

Carbon Nanotube Mode Locked Soliton Fibre laser

aipt_fibrelaser1
Soliton is an ultra-short optical pulse with
properties having significant impact on the
optical communication. AIPT has recently
studied  the  Carbon  Nanotube  enabled
ultrafast  fibre  laser  technology  which  is
able to produce soliton pulses with a more
compact  structure.  With  the  nanomaterial
enabled  photonics  technology,  AIPT  is
considering    both  commercialisation  and
fundamental research in this type of laser.

Truly all fibre
•  Light weight and compact
•  Ultrashort pulse generation (10-15s)•  Soliton pulse shape
•  Low cost
•  Environmentally stable
