While we're at it:  use a tight grid of diode
lasers and see if they'll
injection
lock together- if they do, it will be an optical
phased array- in short, a
(nearly) monochromatic (and rather expensive)
flashlight!

The LED is a non-linear device. Would produce

they do work at a pretty high frequency, maybe

they could be used in a

microwave/millimeter wave beacon!! hihi

N6BV of Force 12 fame wrote a book that devoted a chapter to light bulb
antennas.  There is a contest on the air for light bulb antennas.  I can't
remember the title, but I  think it had "light" in the title.  I have it on
PDF, but I can't find it,

Happy Thanksgiving to you all.

I was afraid someone would call me on that.  But
lenses
have their place, too.

While we're at it:  use a tight grid of diode
lasers and see if they'll
injection
lock together- if they do, it will be an

optical

phased array- in short, a
(nearly) monochromatic (and rather expensive)
flashlight!

The LED is a non-linear device. Would

they do work at a pretty high frequency,

maybe

they could be used in a

microwave/millimeter wave beacon!! hihi

N6BV of Force 12 fame wrote a book that devoted a chapter to light bulb antennas. There is a contest on the air for light bulb antennas. I can't remember the title, but I think it had "light" in the title. I have it on PDF, but I can't find it, Happy Thanksgiving to you all.

Dave, et al,

The book is "Array of Light" by Tom Schiller, N6BT.  I have a copy.
It's a good book...really disorganized, but a lot of good notes, tips,
designs, and anecdotes.

His motivation is the thesis "Everything works [as an antenna]."  This
is certainly quite true at HF, probably less true at higher
frequencies, but it's all about closing the link budget.

73,
