1. An optical module, comprising:
a carrier;
an optical emitter disposed over the carrier;
a monitor disposed over the carrier and configured to adjust a property of a first light emitted from the optical emitter;
a first optical component configured to receive the first light and radiate a second light and a third light, wherein the monitor comprises a first optical receiver and a controller, and wherein the first optical receiver is configured to receive the second light and generate an electrical signal to the controller, and the controller is configured to adjust the property of the first light emitted from the optical emitter based on the electrical signal;
a second optical receiver configured to receive a reflected light of the third light from an object, wherein the monitor is configured to adjust the property of the first light emitted from the optical emitter so as to keep a property of the reflected light within a predetermined range.
