About Alain Haché
- Alain Haché (born 14 December 1970, in Tracadie, New Brunswick) is an experimental physicist, a professor at the University of Moncton, Canada.
- From 2003 to 2013 he held the Canada Research Chair in Photonics.
- He is also the author of The Physics of Hockey and Slap Shot Science, two popular science books on ice hockey. In 2002, he and undergraduate student Louis Poirier transmitted faster-than-light electrical pulses through a 120-metre long "photonic crystal" made of coaxial cables of alternating characteristic impedance (12 pairs of 50 O and 75 O cables).
- The experiment showed that the pulse envelope was recreated at the end of the cables at a speed of >3 c.
- This speed represents the group velocity, but the amplitude of the signal also drops in such a way that the energy transmitted never exceeds, at any given time, the energy that would have been transmitted by same pulse travelling in a vacuum.
