1. A method for optical signal communication, the method comprising:
(a) providing a hollow fiber comprising a media disposed in at least a portion of a hollow space of the hollow fiber, the media comprising media members, the media members being dispersed, the media members comprising molecules or atoms, the hollow fiber having a first end and a second end opposing the first end, the hollow fiber being configured for the optical signal communication comprising transmission of a signal through the hollow fiber from the first end to the second end, the signal comprising electromagnetic radiation;
(b) transmitting a first laser beam into the hollow fiber to excite at least one member of the media members such that the at least one member excited by the first laser beam emits a first Raman radiation upon relaxation, the first Raman radiation having a wavelength; and
(c) modulating a second laser beam to carry the signal utilized for the optical signal communication and transmitting the second laser beam carrying the signal through the hollow fiber, the second laser beam carrying the signal being enhanced by the first Raman radiation having the wavelength, the second laser beam being enhanced during its propagation through the hollow fiber,
wherein the media members comprise a first member type and a second member type, wherein the first laser beam excites the first member type that subsequently emits the first Raman radiation, and wherein a third laser beam excites the second member type that subsequently emits a second Raman radiation having the wavelength.
