Caption: XRD, Er3+ concentration (+-1mol%), lifetime t (+-0.5ms) and bandwidth FWHM (+-0.5nm) for the 4I13/2 erbium level of as-deposited amorphous waveguide (WG1), CG waveguides obtained by one-step process (WG3, WG4, WG5) and CG waveguide obtained by two-step process (WG2T). The population ratio of each erbium site is given in brackets

You are provided with a table from a material science paper. Here are JSON templates for two types of numeric cells: "Other" and "Glass_Compound_Amount":
{"value": "xx", "type": "Other"}
{"value": "xx", "type": "Glass_Compound_Amount", "constituent": "xx", "unit": "xx", "material": "xx"}

Please describe all numeric cells in the above table following the JSON templates (proceeding by row in a left-right, top-down direction). For each cell, output one JSON description per line. For any unanswerable attributes in the templates, set their value to the placeholder "xx".
