Optical micro-modules include a laser mount having an integrated light emitter, an integrated lens holder, and an integrated microlens. The microlens, which preferably collimates light received from the light emitter, is attached to a front surface of the lens holder and aligned with the light emitter. The light emitter and the lens holder are affixed side by side on a substrate in the micro module so that the microlens can be aligned with the light emitter during fabrication of the micro-module at the wafer level rather than during later assembly. A ball lens may optionally be used to focus the light exiting the microlens into an optical fiber. An optical isolator, a thermoelectric cooler, and/or a back monitor, such as a wavelength locker, are also preferably incorporated.
