Claim 0:
1. A tunable laser based light source for Li-Fi communication comprising:
a laser for emitting, in operation, a scanning beam,
a first optical element configured to reflect and/or refract the scanning beam emitted from the laser, and
a second optical element configured to broaden the scanning beam reflected/refracted by the first optical element,
wherein the scanning beam is configured to scan a scanning area,
wherein the scanning area is extending with a first scanning length in a broadening direction and a second scanning length in a scanning direction,
wherein the broadening direction and the scanning direction are mutually perpendicular,
wherein the second optical element is configured to broaden the scanning beam in the broadening direction to a width larger than the first scanning length, and
wherein the laser and the first optical element are configured to cooperate to enable the scanning beam to be swept along the scanning direction.
