A network for communicating a message is established by providing a network that includes topographic network devices and communication links interconnecting the topographic network devices. The topographic network devices each have a physical location represented by a topographic coordinate set. A network address is assigned to each of the topographic network devices. The network address includes the topographic coordinate set of the topographic network device. The topographic coordinate set of the topographic network device is transmitted to those of the topographic network devices directly connected to the topographic network device. The topographic coordinate set of the topographic network device is received and stored at at least one of the topographic network devices directly connected to the topographic network device.

Method for establishing a communication network based on topographic network devices and for transmitting a message through same

The tunable optical filter includes an elastic substrate, a diffractive element in the elastic substrate, an actuator for stretching the elastic substrate to control the pitch of the diffractive element, a first optical path and a second optical path. The diffractive element optically couples the second optical path to the first optical path at an optical frequency determined by the pitch of the diffractive element.
