They exist in the form of bipolar (Red/Green)
LEDs. You can actually get most any color you
want, so perhaps they could make Red/Red super-
bright if you would but ask (and order 50K pcs.)

There are also "AC input" optocouplers that have
inverse parallel IR Leds internally. Popular for
some applications, such as AC voltage input to
microcontrollers (even PICs).
