From the appearance of these micro-scale LED's, they should permit simple automated production to produce many copies to cover a macro-scale area to generate light even at gigawatt power levels. The first report discusses micro-scale LED's whose light output scales up to 300 W per square centimeter, 3 megawatts per square meter. Optical communications using coherent and non-coherent light. The MicroLEDs semiconductor manufacturing process includes construction of a parabolic reflector to enable optimal light control and high efficiency from micro-meter-sized LEDs. InfiniLED MicroLEDs achieve 300 W/cm2 output density from tiny source. I wondered about this because of two reports I saw doing a web search actually on optical communication: At current prices this would cost billions of dollars.īut is it possible to do it without using lasers, just using high intensity noncoherent light focused by mirrors or lenses? So to launch thousand kilo payloads would require a gigawatt laser power levels. The estimate of the payload you can launch to Earth orbit dependent on laser power is about 1 kg per megawatt. The problem is the initial cost outlay for the lasers is still prohibitive to launch a sizable payload.
We now have the capability to do laser launch.
