A1 González Herráez, Miguel K1 Flexible control K1 Negative group velocities K1 Ciencias tecnológicas K1 Electrónica K1 Technology K1 Electronics AB A method to achieve an extremely wide and flexible control of the group velocity in an optical fiber is presented. Group velocities below 71,000 km/s on one hand, well exceeding the speed of light in vacuum on the other hand and even negative group velocities can readily be obtained.
