I guess seriously parallel rays are difficult to achieve in the first 
place - with one notable solution happening to be the laser.

To achieve parallel rays with optics - whether conventional or fiber 
optics - you either need a sufficiently point-like light source, or one 
that's far away enough to appear sufficiently point-like. The sun 
doesn't really fit that bill. Light from some other star would probably 
be fine, if it wasn't for the lack in intensity.
