Abstract

Disclosed is a method that enables a single client to communicate with many tunable lasers, or many clients to communicate with a single laser. Benefits include the ability of the method to run on any computer in a networked environment.

An Inexpensive, Scalable, and Remote Communication Technique for Tunable Laser Development and Manufacturing

Disclosed is a method that enables a single client to communicate with many tunable lasers, or many clients to communicate with a single laser. Benefits include the ability of the method to run on any computer in a networked environment.

Background

Currently, a computer serial port is used to communicate directly with the microprocessor of the system being developed. This supports a single client only, and remote access to the system is limited to the maximum allowable cable length specified by the applied hardware protocol.

General Description

Figure 1 shows the architecture of the disclosed method described in the following sections.

Laser Server Implementation

The server is software running on the laser's microprocessor. For simplicity, a single command may be processed at a time. Bytes are received, processed, and results are returned with no understanding of client identity.

Proxy Interface with Laser

Transmission of bytes between the proxy and a laser is accomplished using standard personal computer peripherals such as a serial port, parallel interface, or USB. If the laser is using a hardware interface not readily available on the computer, such as the Serial Peripheral Interface (SPI) or the Inter-Integrated Circuit Bus (I2C) an adapter can be used to convert between protocols.

Client Interface with Proxy
