PROBLEM TO BE SOLVED: To provide the design, packaging, and manufacturing of direct-modulated analog external cavity lasers (ECLs) for analog and semi-analog (such as quadrature amplitude modulated (QAM)) signals, particularly for broadcast, digital simulcast and narrowcast (QAM) applications. SOLUTION: The design of direct-modulated analog ECLs is performed with simultaneously controlling chirp, low intermodulation distortions, and low relative intensity noise (RIN) which provide high performance and low cost devices, methods and/or systems for transmission of analog signals.
