Analog to digital pulse output IC?

I'm looking for an IC that takes an analog input and outputs the data through a single output (whether it is a stream of data bits, or just pulling a line high for x msecs, it doesnt matter). The idea is that this would be used in a fiber optic system where a sensor will send data to a host, only one way. Are there any ICs like this and what are they called? Thanks!

I think that is along the lines of what I want, but there can't be any communication from the host to the sensor. I'm imagining a single unidirectional fiber optic line, so on the sensor end it will just constantly send the data no matter what the conditions are on the other end.

Possibly some kind of analog circuit where the voltage input determines either the frequency or wavelength of the output?

Edit: duh, 555 timer! Can't believe I didn't think of it earlier :)

Edit 2: Solved my problem. Voltage output of a sensor goes into the control pin of the 555 to adjust the square wave:
