Bandwidth Tuneable Filters

Through cascading a low-pass tuneable edge filter with a long-pass tuneable edge filter, one can achieve a new type of bandwidth-tuneable filter whose pass band width is variable while its centre wavelength is still tuneable. With such a device, you can

• Change passband width
• Tune centre wavelength
